Question: question 3 given samples from two populations that you know...
Given samples from two populations that you know are normally distributed. You don't known the population variances. The sample mean and standard deviation from a sample of size 6 from population A is 16.5 and 1.1, respectively. The sample mean and standard deviation from a sample of size 4 from population B is 12.5 and 3.1, respectively.
Conduct a one-sided hypothesis test with alpha = .05 that the population means are equal versus the alternative that the mean of A is greater than the mean of B.
What is the value of the test statistic, ?
What is the approximate degrees of freedom for this test (i.e., what is the computed value of v)?
What is the value associated with the critical region, ?
If you would reject the null hypothesis, enter 1;
If you would fail to reject the null hypothesis, enter 2.
