In a recent awards ceremony, the age of the winner for best actor was 31 and the age of the winner for best actress was 42. For all best actors, the mean age is 42.4 years and the
standard deviation is 8.2 years. For all best actresses, the mean age is 31.6 years and the standard deviation is 10.3 years. (All ages are determined at the time of the
awards ceremony.) Relative to their genders, who had the more extreme age when winning the award, the actor or the actress? Explain.
Since the z score for the actor is z= and the z score for the actress is z-, the
had the more extreme age.
