For each test below, follow the following steps. (1) state the hypotheses, (2) formulate an analysis plan (3) analyze sample data (4) interpret the results You may use the TI-83 to calculate the test statistic and p-value, but be sure you indicate which test you are using.

Test III – Test a New Drug (Part 2) Suppose the Acme Drug Company develops a new drug, designed to prevent colds. The company states that the drug is more effective for women than for men. To test this claim, they choose a simple random sample of 100 women and 200 men from a population of 100,000 volunteers. At the end of the study, 38% of the women caught a cold; and 51% of the men caught a cold. Based on these findings, can we conclude that the drug is more effective for women than for men? Use a 0.01 level of significance.

1: Conduct the following hypothesis test. Specify the null and alternative hypotheses, and clearly state the conclusion of the test. Use the data from 6.3.3 (?̅ = 31.7, ? = 8.7, ? = 5). Is there enough evidence to conclude that the mean thymus weight is greater than 25mg? Set ? = 0.05 2: Suppose we used a two-tailed alternative for the previous test instead (thymus weight is not equal to 25mg). How would the p-value of the test change?...
