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 that the awards were presented. complete parts (a) and (b) below. actress left parenthesis years right parenthesis 27 29 32 27 37 28 26 45 28 36 actor left parenthesis years right parenthesis 62 37 38 37 30 36 48 41 39 42 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 0 (indicating that the best actresses are generally younger than best actors). in this example, mu subscript d 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?
