Assume that the distributions of the amounts spent per month on reading and enter- tainment for the particular population of males and females who are between 30 and 40 years old are normal with means and standard deviations given in the following table: 2. Gender Males Mean $88.0 $112.5 Standard deviation $20.0 Females $25.0 If we randomly select a group of two men and two women who are between 30 and 40 years old in this population, what is the probability that at least one of them has spent more than $120? Assume that their expenditures are independent.
