Suppose that the distribution of iq's of north catalina state university's students can be approximated by a normal model with mean 130 and standard deviation 8 points. also suppose that the distribution of iq's of chapel mountain university's students can be approximated by a normal model with mean 120 and standard deviation 10 points. question 1. you select 3 students at random from each school. what is the probability that the mean iq of the 3 north catalina students is at least 5 points higher than the mean iq of the 3 chapel mountain students?
