Two random samples are selected from two independent populations. A summary of the samples sizes, sample means, and sample standard deviations is given below:

n1=41, n2=44, x¯1=52.3, x¯2=77.3, s1=6 s2=10.8

Find a 96.5% confidence interval for the difference μ1−μ2 of the means, assuming equal population variances.
