Sample: n = 30

Avg Score: = 7.00

Standard deviation: = 2.50

Data:

4, 7, 6, 10, 6, 3, 8, 1, 5, 3, 8, 2, 4, 9, 3, 9, 5, 8, 10, 6, 3, 4, 9, 10, 7, 5, 3, 5, 8, 4

Set the criteria for a decision:

If you decide to use an alpha level of .05, what is the z-score that you will use as a cutoff score for the hypothesis test?

If you decide to use an alpha level of .01, what is the z-score that you will use as a cutoff score for the hypothesis test?

If you decide to use an alpha level of .001, what is the z-score that you will use as a cutoff score for the hypothesis test?

-Collect data & compute sample statistics What is the sample mean (M)?

What is the z-score that corresponds with this sample mean?
