The null and alternate hypotheses are:
H0: mean of 1 is equal to the mean of 2
H2: mean of 1 is not equal to the mean of 2
A random sample of 15 observations from the first population revealed a sample mean of 350 and a sample standard deviation of 12. A random sample of 17 observations from the second population revealed a sample mean of 342 and a sample standard deviation of 15.
At the .10 significance level, is there a difference in the population means?© BrainMass Inc. brainmass.com June 3, 2020, 7:02 pm ad1c9bdddf
