Provide a 90% confidence interval for the difference between the two population means. Provide a 95% confidence interval for the difference between the two population means.

a.

To determine

Find the point estimate of the difference between the two population means.

### Explanation of Solution

Calculation:

The results from two independent random samples drawn from two populations are as follows:

 Sample 1 Sample 2 n1=50 n2=35 x¯1=13.6 x¯2=11.6 σ1=2.2 σ2=3

b.

To determine

Find the 90% confidence interval for the difference between two population means.

c.

To determine

Find the 95% confidence interval for the difference between two population means.
