(1 point) Two random samples are selected from two independent populations. A summary of the samples sizes, sample means, and sample standard deviations is given below: ni = 51, 1 = 50.2, 2 = 40, Z = 79.4, 81 = 5.4 82 = 10.6 Find a 95.5% confidence interval for the difference Lii – 12 of the means, assuming equal population variances. Confidence Interval =
