You have a sample size of N = 20. You will perform a one-tailed t-test with...

You have a sample size of N = 20.

You will perform a one-tailed t-test with alpha = .05. You have looked up the critical value and it is -1.73. You have calculated t-test statistics of -1.41.

Which of the following is correct?

Reject the null or retain the null?

You have a sample size of N = 37 and you are going to perform a one-sample t-test using alpha = .05. You go to the t-table and find that there is no entry for this - you have to choose between the critical values at df = 30 or df = 40.

You SHOULD use df = 30 because:

a)	this increases the likelihood that you will reject the null

b)	it is less conservative than using 40

c)	it is more conservative than using 40

d)	this increases the likelihood that you will make a Type I error
