A research facility claims that more than 74.4% of women in a certain age group are taller than 61.8 inches. In a random sample of 152 women from that group approximately 122 are taller than 61.8 inches. At the determined level of significance below check if there is enough evidence to support the facility’s claim. a. Display the hypothesis structure, identify the claim and the test type b. Find the p-value and indicate if the null hypothesis should be rejected or not. p = c. Circle one: Reject Null hypothesis Fail to reject Null hypothesis Circle one: Reject Claim Accept Claim d. Write your verbal conclusion about the claim at the 4% level of significance. e. Would the result change if the test was performed at the 3% level of significance? Explain.

Identify the test statistic for this hypothesis. Identify the P-Value for the hypothesis test. Identify the conclusion for the hypothesis. Do the results support the belief that 50.7% of newborn babies are boys?

Since an instant replay system for tennis was introduced at a major tournament, men challenged 1394 referee calls, with the result that 428 of the calls were overturned. Women challenged 755 referee calls, and 230 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.

An Office of Admission document claims that 55.6% of UVA undergraduates are female. To test this claim, a random sample of 205 UVA undergraduates was selected. In this sample, 55.4% were female. Is there sufficient evidence to conclude that the document's claim is false? Is the percent of undergraduate females different from what is claimed? Carry out a hypothesis test at a 9% significance level. A. The value of the standardized test statistic (give to at least 3 decimal places): B. The p-value is (give to 4 decimal places) C. Your decision for the hypothesis test: OA. Do Not Reject Ho OB. Reject H,- OC. Do Not Reject H1. OD. Reject Ho-
