Question
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=7878,
xequals=35.935.9
years, and
sequals=11.411.4
years. Use a
0.050.05
significance level to test the claim that the mean age of actresses when they win an acting award is
3232
years.What are the hypotheses?
Upper H 0H0:
muμequals=3232
yearsUpper H 1H1:
muμless than<3232
yearsUpper H 0H0:
muμequals=3232
yearsUpper H 1H1:
muμnot equals≠3232
yearsUpper H 0H0:
muμequals=3232
yearsUpper H 1H1:
muμgreater than or equals≥3232
