a. Use a 0.10 significance level to test the claim that Oscar-winning actresses tend to be younger than Oscar-winning actors. In this example, " 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 actor's age minus the actress's age. What are the null and alternative hypotheses for the hypothesis test? Ho: Hd #₁: Ha years years Type integers or decimals. Do not round.) dentify the test statistic. =(Round to two decimal places as needed.) identify the P-value. P-value = (Round to three decimal places a needed.) What is the conclusion based on the hypothesis test? Since the P-value is the significance level, the null hypothesis. There sufficient evidence to support the claim that Oscar-winning actresses tend to be younger than Oscar-winning actors. b. Construct the confidence interval that could be used for the hypothesis test described in part (a). What feature of the confidence interval leads to the same conclusion reached in part (a)? The confidence interval is year(s)< < year(s). (Type integers or decimals rounded to one decimal place as needed.) What feature of the confidence interval leads to the same conclusion reached in part (a)? Because the confidence interval includes H₂-
