3. the college student journal (dec. 1992) investigated differences in traditional and nontraditional students, where
nontraditional students are generally defined as those 25 years or older. based on the study results, we can assume that the
population mean and standard deviation for the gpa of all nontraditional students are 3.5 and 0.5, respectively. suppose
that a random sample of n = 100 nontraditional students is selected from the population of all nontraditional students, and
the gpa of each student is determined. what is the approximate probability that the nontraditional student sample has a
mean gpa between 3.40 and 3.60?
