1.What are the two formulas for the standard error, SM in a T test?

2.If a variance is 100, what is the SD? (this question is as simple as it appears?)

3.If a SD is 30, what is the variance? (this question is as simple as it appears)

4.A sample of n = 25 scores has a mean of M = 50 and a variance of s2 = 36. What is the estimated standard error for the sample mean (consider the information here carefully, what about it is important and what is not)?

5.A sample of n = 49 scores has a mean of M = 32 and a SM of 5. What is the variance of this sample? (this is an algebra problem!)

6.What is the standard deviation for problem #5?

7.What happens to the standard error when you decrease the variance?

8.In the one sample T test, what happens to the DF when you decrease the sample size?

9.If I go from 15 DF to 20 DF what happens to the critical value of T and why (2 points)

10.What is the formula for the one sample T test?

11.If the alpha for a hypothesis test is .05, and the P value you get for your sample T is .08, can you reject the null or not? And why?
