# Question: question 3 given samples from two populations that you know...

###### Question details

Question 3:

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.
