The following data lists the ages of a random selection of actresses when they won an award in the category of Best Actress, along with the ages of actors when they won in the category of Best Actor. The ages are matched according to the year hat the awards were presented. Complete parts (a) and (b) below. Actress (years) 27 Actor (years) 31 29 31 34 23 28 37 33 31 O 67 41 36 42 26 35 46 40 37 39 APH: year(s) H: Ha year(s) Type integers or decimals. Do not round.) dentify the test statistic. (Round to two decimal places as needed.) dentify the P-value. P.value = (Round to three decimal places as needed.) What is the conclusion based on the hypothesis test? Since the P-value is v the significance level, V the null hypothesis. There V sufficient evidence to support the claim that actresses are generally younger when they won the award than actors. o. 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)
