Question
a. Use the sample data with a 0.01 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 0? (indicating that the Best Actresses are generally younger than Best Actors).
In this example, ud 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?
Identifv the test statistic
(Round to two decimal places as needed.)
Identify the P-value
P-value = (Round to three decimal places as needed.
based on the hypothesis test,
Since the P-value is _____
the significance level, ____ the null hypothesis . There ____ sufficient evidence to support the claim that actresses are generally younger when they won the award than actors.
Construct the confidence interval.
What feature of the confidence interval leads to the same conclusion reached in part (a)?
since the confidence interval contains _____ ____ the null hypothesis.
