for a hypothesis test of difference of means, we can do a hypothesis test for _______________________________________________ to see if there is sufficient evidence that the assumption of _______________________________________ is not met.

when a hypothesis tests for difference of means is done, assuming the assumptions of the test are met, we use a t-distribution because________________________________________.

Solution

for a hypothesis test of difference of means, we can do a hypothesis test for ___________normality____________________________________ to see if there is sufficient evidence that the assumption of ________________Normal distribution_______________________ is not met.

when a hypothesis tests for difference of means is done, assuming the assumptions of the test are met, we use a t-distribution because________population standard deviation is unknown________________________________.
