Question
Two random samples are selected from two independent populations. A summary of the samples sizes, sample means, and sample standard deviations
is given below:
n = 51, š = 57.1, s =5.4
n - 52, = 78.6, 3 = 11
Find a 92.5% confidence interval for the difference H- H2 of the means, assuming equal population variances.
Confidence Interval =
