Math Problem Statement
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
nequals=8282,
xequals=35.335.3
years, and
sequals=11.111.1
years. Use a
0.010.01
significance level to test the claim that the mean age of actresses when they win an acting award is
3333
years.
