Question

Given two independent random samples with the following results:

n1=7x‾1=179s1=22n1=7x‾1=179s1=22   n2=14x‾2=145s2=20n2=14x‾2=145s2=20

Use this data to find the 80% confidence interval for the true difference between the population means. Assume that the population variances are not equal and that the two populations are normally distributed.

Step 1 of 3 :  

Find the point estimate that should be used in constructing the confidence interval.

Step 2 of 3 :  

Find the margin of error to be used in constructing the confidence interval. Round your answer to six decimal places.

step 3 of3: construct the 80% confidence interval.Round your answers to nearest whole number.
