The ages of actresses when they won an acting award is summarized by the following data: The sample size is 77, the sample mean is 35.8 years, and the standard deviation of the sample is 11.6 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. Use a scrap piece of paper to write out your steps to solve this problem...hypothesis testing problems are very difficult to work in your head! Use your calculator to perform a Z-Test or T-Test since this is a hypothesis test for the mean. What are the hypotheses? A. Ho: H33 years В. Но: и3 33 уears H1 H33 years H1: 33 years O D. Ho: H 33 years H1 H 33 years C. Ho: H 33 years H H33 years Identify the test statistic (Round to two decimal places as needed.) Identify the P-value. The P-value is (Round to four decimal places as needed.)
