# Question: Refer to the information given in Exercise 10 3 Test at

Refer to the information given in Exercise 10.3. Test at a 5% significance level if the two population means are different.

n1 = 18 1 = 7.82 σ1 = 2.35

n2 = 15 2 = 5.99 σ1 = 3.17

n1 = 18 1 = 7.82 σ1 = 2.35

n2 = 15 2 = 5.99 σ1 = 3.17
