You wish to test Hozpl = pig versus Ha : pal 7E pig at a = 0.10. You obtain a sample of size 11.1 = 8 with a mean of 1 : 82.7 and a standard deviation of 31 : 9.4 from the first population. You obtain a sample of size n2 = 10 with a mean of 5:2 = 93.1 and a standard deviation of .32 = 12.9 from the second population. Assume that the populations are normal with equal variances. Do not round interim calculations. Round your final answers to three decimal places. (a). Find the test statistic: C]
