# Setting Up Hypotheses

## Type I and Type II Errors

### Questions

**Question 1 out of 5.**

It has been shown many times that on a certain memory test, recognition is substantially better than recall. However, the probability value for the data from your sample was.12, so you were unable to reject the null hypothesis that recall and recognition produce the same results. What type of error did you make?

- Type I
- Type II

**Question 2 out of 5.**

In the population, there is no difference between men and women on a certain test. However, you found a difference in your sample. The probability value for the data was.03, so you rejected the null hypothesis. What type of error did you make?

- Type I
- Type II

**Question 3 out of 5.**

As the alpha level gets lower, which error rate also gets lower?

- Type I
- Type II

**Question 4 out of 5.**

Beta is the probability of which kind of error?

- Type I
- Type II

**Question 5 out of 5.**

If the null hypothesis is false, you cannot make which kind of error?

- Type I
- Type II
