A) Does this provide statistically significant evidence at the 1% significance level that the rule changes has decreased the likelihood of an athlete needing reconstructive surgery. You may use an app to do the test. If you do so, you must insert a screenshot of your work and also specifically identify the following: • Identify the null and alternative hypothesis, be sure to use appropriate notation. Justify your choice of null hypothesis from the context of the problem. • Identify the procedure or app you used. • Identify the test statistic and associated p-value • State the conclusion of the hypothesis test. Include the statistical justification for the conclusion. B) Put the result of your test into the context of the problem. Does the hypothesis test support the claim that the rule changed decreased the likelihood of the injury requiring reconstructive surgery? Why or why not? Justify your argument using the results of your hypothesis test. C) Someone questions the results of your study by criticizing your sample size. Is this a valid criticism? Explain.

Answer the questions in the picture please, explain each answer please! Thank you!
Transcribed Image Text:4) 35% of high school athletes who needed surgery for this injury required a reconstructive surgery. Rules were adjusted to make this type of injury less
frequent. In the year following the rule change, the athletic found in a random sample of 112 injuries 32 required the reconstructive surgery.
A) Does this provide statistically significant evidence at the 1% significance level that the rule changes has decreased the likelihood of an athlete needing
reconstructive surgery. You may use an app to do the test. If you do so, you must insert a screenshot of your work and also specifically identify the
following:
• Identify the null and alternative hypothesis, be sure to use appropriate notation. Justify your choice of null hypothesis from the context of the problem.
• Identify the procedure or app you used.
• Identify the test statistic and associated p-value
• State the conclusion of the hypothesis test. Include the statistical justification for the conclusion.
B) Put the result of your test into the context of the problem. Does the hypothesis test support the claim that the rule changed decreased the likelihood of
the injury requiring reconstructive surgery? Why or why not? Justify your argument using the results of your hypothesis test.
C) Someone questions the results of your study by criticizing your sample size. Is this a valid criticism? Explain.
