Math Problem Statement
Question content area top Part 1 Assume that a simple random sample has been selected and test the given claim. Use the P-value method for testing hypotheses. Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim. The ages of actresses when they won an acting award is summarized by the statistics nequals82, xequals35.3 years, and sequals11.1 years. Use a 0.01 significance level to test the claim that the mean age of actresses when they win an acting award is 33 years. Question content area bottom Part 1 What are the hypotheses? A. Upper H 0: muequals33 years Upper H 1: mugreater than or equals33 years B. Upper H 0: muequals33 years Upper H 1: muless than33 years C. Upper H 0: munot equals33 years Upper H 1: muequals33 years D.
