Since an instant replay system for tennis was introduced at a major tournament, men challenged 1415 referee calls, with the result that 425 of the calls were overturned. Women challenged 755 referee calls, and 210 of the calls were overturned. Use a 0.05 significance level to test the claim that men and women have equal success in challenging calls. Complete parts (a) through (c) below.
a. Test the claim using a hypothesis test.
Consider the first sample to be the sample of male tennis players who challenged referee calls and the second sample to be the sample of female tennis players who challenged referee calls. What are the null and alternative hypotheses for the hypothesis test?
A.
H0: p1=p2
H1: p1≠p2
B.
H0: p1≠p2
H1: p1=p2
C.
H0: p1=p2
H1: p1 p2
F.
H0: p1≤p2
H1: p1≠p2
Identify the test statistic.
z=nothing
(Round to two decimal places as needed.)
Identify the P-value.
P-value=nothing
(Round to three decimal places as needed.)
What is the conclusion based on the hypothesis test?
The P-value is
▼

the significance level of α=0.05, so
▼

the null hypothesis. There
▼

evidence to warrant rejection of the claim that women and men have equal success in challenging calls.
b. Test the claim by constructing an appropriate confidence interval.
The 95% confidence interval is nothing
(Round to three decimal places as needed.)
What is the conclusion based on the confidence interval?
Because the confidence interval limits
▼

0, there
▼

appear to be a significant difference between the two proportions. There
▼
is sufficient
is not sufficient
evidence to warrant rejection of the claim that men and women have equal success in challenging calls.
c. Based on the results, does it appear that men and women may have equal success in challenging calls?
A.
The confidence interval suggests that there is a significant difference between the success of men and women in challenging calls. It is reasonable to speculate that women have more success.
B.
The confidence interval suggests that there is a significant difference between the success of men and women in challenging calls. It is reasonable to speculate that men have more success.
C.
The confidence interval suggests that there is no significant difference between the success of men and women in challenging calls.
D.
There is not enough information to reach a conclusion.
What is the median of 12, 9 , 16, 1, 6 , 5, 84
The median of your data would be 9.
First, align the numbers from least to greatest:
1, 5, 6, 9, 12, 16, 84
Next, identify which number is in the middle; if you have a hard time figuring that out you may want to strikethrough numbers on both sides until you have only one number left—that would be your median per se (i.e., 9 is the median of this data set).

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.

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.
In most of the U.S. states, there could be more lawn than any single irrigated crop. This decrease in the production possibilities curve means that the U.S. is operating inefficiently and hence it is at a point which isi inside of the production possibility curve in the 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.
