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=p2H1: p1p2B.H0: p1p2H1: p1=p2C.H0: p1=p2H1: p1 p2F.H0: p1p2H1: p1p2Identify 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 less thangreater than the significance level of =0.05, so rejectfail to reject the null hypothesis. There is not sufficientis sufficient 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 includedo not include 0, there doesdoes not appear to be a significant difference between the two proportions. There is sufficientis 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.
I'm so sorry I know this is long but can someone please help me with this?I would be forever gratefulJohn 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 Johns 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 Johns presenting symptoms and test results2. 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.
