summary statistics are given for independent simple
random samples from two populations. Use the nonpooled t-test to
conduct the required hypothesis test.
1 = 72.8, s 1 = 10.9, n
1 = 16, 2 = 69.9,
s 2 = 8.2, n 2 = 12
Perform a right-tailed hypothesis test using a significance level
of α = 0.05.
Test statistic: t = 2.635 |
