Question

1. The 2004 General Social Survey asked a random sample of 977 adult Americans how often they feel rushed with three options to choose from: always, sometimes, and never. a. State the null and alternative hypotheses for testing the following claim: Over one-third of all adult Americans always feel rushed. b. In the sample of 977 adult Americans, 304 responded that they always feel rushed. Explain how the conditions for the use of the central limit theorem are satisfied. c. Calculate the value of the test statistic. d. Calculate the p-value. e. Interpret what this p-value means in this context. (Hint: The p-value is the proba- bility of what, assuming what?) f. State your test decision at the a = 0.05 significance level. g. Summarize your conclusion in the context of the study.
