# Question: Refer to the information given in Exercise 10 18 Test at

Refer to the information given in Exercise 10.18. Test at a 5% significance level if µ1 is greater than µ2.

n1 = 55 1 = 90.740 s1 = 11.60

n2 = 50 2 = 86.30 s1 = 10.25

n1 = 55 1 = 90.740 s1 = 11.60

n2 = 50 2 = 86.30 s1 = 10.25
