Consider two independent random samples of sizes 17 1 = 15 and 1= = 14, taken from two normally distributed populations . Thesample standard deviations are calculated to be 54 = 4 4 and 5= = 9.5, and the sample means are * 1 = 78. 31 andIn = $0. 4 4, respectively!& ) Calculate a point estimate for the difference in population means , # 1 - #``
