In Random Samples of 25 and 22 from Each of Two

question 15

Short Answer

In random samples of 25 and 22 from each of two normal populations, we find the following statistics: $\bar { X } _ { 1 }$ = 56, s1 = 8. $\bar { X } _ { 2 }$ = 62, s2 = 8.5.
Assume that the population variances are equal. Estimate with 95% confidence the difference between the two population means.
