a. Use the sample data with a 0.05 significance level to test the claim that for the population of ages of Best Actresses and Best Actors, the differences have a mean less than
O (indicating that the Best Actresses are generally younger than Best Actors).
In this example, Hg is the mean value of the differences d for the population of all pairs of data, where each individual difference d is defined as the actress's age minus the
actor's age. What are the null and alternative hypotheses for the hypothesis test?
Họ: Ha = 0 year(s)
H: Ha o year(s)
(Type integers or decimals. Do not round.)
Identify the test statistic.
t- (Round to two decimal places as needed.)
