Question 68

Essay

Assume that the population distributions of ages (in years) of students at two different universities in Ontario are normal with equal variances. Two random samples, drawn independently from the populations, showed the following statistics: Assume that the population distributions of ages (in years) of students at two different universities in Ontario are normal with equal variances. Two random samples, drawn independently from the populations, showed the following statistics: = 10, = 25, = 4; = 9, = 24, and = 9. Construct and interpret a 99% confidence interval for the true difference in average ages of students at each university. = 10, Assume that the population distributions of ages (in years) of students at two different universities in Ontario are normal with equal variances.
