The value for the degrees of freedom for Mark's sample population is six. The t-distribution that Mark uses has thicker tails than a standard normal distribution. The correct options are A and D.
What is a t-test?When the population standard deviation is unknown, the student's t-test is a statistical tool for assessing assumptions about the mean of a small sample taken from a normally distributed population.
A statistical test called a t test is employed to compare the means of two groups. It is frequently employed in hypothesis testing to establish whether a procedure or treatment truly affects the population of interest or whether two groups differ from one another.
Using a one-sample t-test, Mark Six is the number of degrees of freedom that apply to Mark's sample population. Mark employs a t-distribution, which has thicker tails than a typical normal distribution.
Thus, the correct options are A and D.

If 7 men 5 women have applied for job and 3 applicants are randomly selected from the probability that 2 are men how many WOmen?
.
The probability of selecting 2 men and a woman is [tex]\frac{21}{44}[/tex]
The sample space is made up of 7 men and 5 women. So we have a total of 12 people.
If 3 applicants are randomly selected without replacement, there will be three mutually exclusive possibilities;
[tex]MMW=\text{Event that a Man, then Man, then Woman is selected}\\MWM=\text{Event that a Man, then Woman, then Man is selected}\\WMM=\text{Event that a Woman, then Man, then Man is selected}\\[/tex]
The final probability will have the form
[tex]P(\text{2 men and 1 woman})=P(MMW)+P(MWM)+P(WMM)[/tex]
because the possibilities are mutually exclusive.
Computing the Probability of each possibilityEach mutually exclusive possibility is made up of dependent events. This is because when selection is done without replacement, it affects the size of the sample space.
The Probability of selecting a Man, then a Man, then a Woman is[tex]P(MMW)=\dfrac{7}{12}\times\dfrac{6}{11}\times\dfrac{5}{10}\\\\=\dfrac{7}{44}[/tex]
The Probability of selecting a Man, then a Woman, then a Man is[tex]P(MWM)=\dfrac{7}{12}\times\dfrac{5}{11}\times\dfrac{6}{10}\\\\=\dfrac{7}{44}[/tex]
The Probability of selecting a Woman, then a Man, then a Man is[tex]P(MWM)=\dfrac{5}{12}\times\dfrac{7}{11}\times\dfrac{6}{10}\\\\=\dfrac{7}{44}[/tex]
Calculate the Probability of getting two men and a womanThe final probability is
[tex]P(\text{2 men and 1 woman})=P(MMW)+P(MWM)+P(WMM)\\\\=\dfrac{7}{44}+\dfrac{7}{44}+\dfrac{7}{44}\\\\=\dfrac{21}{44}[/tex]

During crawfish season, Xavier sells crawfish for $62.50 per sack and charges a $20.00 delivery fee. Write an equation that could be used to determine y, the total cost of x sacks of crawfish delivered to a customer.
Answer:
62.50x+20=y
Explanation:
The correct equation is - 62.50x+20=y. Therefore 62.50x+20=y is the correct response.
What is an Equation?A mathematical equation is a formula that uses the equals sign to represent the equality of two expressions.
A function is an equation with a single solution for y for each value of x. Each input of a certain type receives precisely one output when using a function. Instead of y, a function is frequently named f(x) or g(x). When x equals 2, we should determine our function's value because f(2) says to do so.
Albert Einstein came up with the equation, generally written as E = mc2, which states that if a body's energy changes by an amount E (in any form), its mass (m) changes by an amount equal to E/c2.
A mathematical statement known as an equation is comprised of two expressions joined together by the equal sign. A formula would be 3x - 5 = 16, for instance. We determine the value of the variable x as x = 7 by solving this equation.

Lawns produce no crops but occupy more land (25 million acres) in the United States than any single crop such as corn or wheat. Does this mean the United States is producing inefficiently (inside the production possibilities curve)? Explain your answer.
Answer:In most U.S. states, there could be more lawn than any single irrigated crop. Hay predominates in the West, however, and in Nebraska and Kansas, there are more acres of corn than anything else
Explanation:
Lawns produce no crops but occupy more land (25 million acres) in the United States than any single crop such as corn or wheat. This means that the US is operating inefficiently and hence is at a point inside the production possibility curve.
What is Production possibility curve?The production possibilities curve is a graph which shows all of the different combinations of the output made which can be produced given the current resources and technology. In total, there are three types of production possibility curves. Namely, the straight line sloping down in the form of concave and convex graph.

John is a 35-year-old male (he/him) administrative assistant who enjoys playing baseball on weekends. During one of their games, John began running from first to second base. As he pushed off to start running, John heard a pop and felt a sharp pain in his right calf as though he had just been kicked in the back of his leg. John fell to the ground and experienced significant pain when putting weight on his right leg. John tried to walk but had to be carried off the field and was taken to the emergency department. At the hospital, it was noted that John had significant swelling at the back of his right leg, had a palpable and visible deformity in the distal calf, and was only able to put small amounts of weight on his right leg. The emergency doctor squeezed the back of John’s right calf and noticed that the ankle would not plantarflex. An x-ray and blood work were ordered which came back without any significant findings.”
Case Study Questions:
1. Explain the possible anatomical structures that were affected by the injury and how each relates to John’s presenting symptoms and test results
2. Identify and explain three differential diagnoses (diseases or conditions that present similar signs and symptoms that could possibly account for the patient's symptoms) with appropriate justifications. After describing your three differential diagnoses, indicate the most likely diagnosis based on your analysis and provide rationale and support for your selection.
3. From an anatomy point of view:
a) Propose a management plan for the most likely diagnosis. This should include the treatment options you would implement given your patient's presenting symptoms. You should provide short- and long-term goals for the patient and a timeline on when you would implement each treatment. There may be several possible treatments you could prescribe to your patient. Include support, justification, and evidence for your prescribed treatment(s) and management plan.
b) Explain the effects of your management plan for your patient's condition. From the management plan you've proposed, what effects will each treatment have on the patient's anatomy? Include any positive and negative effects this plan may have on the patient.

Select two symbols that represent a parameter.
a.)mu
b.)x with bar on top
c.)sigma
d.)p with hat on top
e.)s
Answer:
b
Explanation:
The two symbols that represent a parameter are x with the bar on top and sigma. Thus, the correct options for this question are B and C.
What do you mean by Parameters?Parameters may be defined as arbitrary constants whose value characterizes a member of a system. It is a special kind of variable that is significantly utilized in a function in order to refer to one of the pieces of data provided as input to the function.
These pieces of data are the values of the arguments with which the function is going to be called/invoked. These sets of instructions are governed through the reference and are hence known as parameters.
X with the bar on top and sigma represents the set of parameters in the computer and technology that performs several sets of instructions and functions with respect to each other.
Therefore, the two symbols that represent a parameter are x with the bar on top and sigma. Thus, the correct options for this question are B and C.

Answer:
“Birth of a Nation”—D. W. Griffith’s disgustingly racist yet titanically original 1915 feature—back to the fore. The movie, set mainly in a South Carolina town before and after the Civil War, depicts slavery in a halcyon light, presents blacks as good for little but subservient labor, and shows them, during Reconstruction, to have been goaded by the Radical Republicans into asserting an abusive dominion over Southern whites. It depicts freedmen as interested, above all, in intermarriage, indulging in legally sanctioned excess and vengeful violence mainly to coerce white women into sexual relations. It shows Southern whites forming the Ku Klux Klan to defend themselves against such abominations and to spur the “Aryan” cause overall. The movie asserts that the white-sheet-clad death squad served justice summarily and that, by denying blacks the right to vote and keeping them generally apart and subordinate, it restored order and civilization to the South.
“Birth of a Nation,” which runs more than three hours, was sold as a sensation and became one; it was shown at gala screenings, with expensive tickets. It was also the subject of protest by civil-rights organizations and critiques by clergymen and editorialists, and for good reason: “Birth of a Nation” proved horrifically effective at sparking violence against blacks in many cities. Given these circumstances, it’s hard to understand why Griffith’s film merits anything but a place in the dustbin of history, as an abomination worthy solely of autopsy in the study of social and aesthetic pathology.
