Question

TRUE OR FALSE

1. A type 2 error occurs when we reject a true null hypothesis

2. All Chi- Square tests are right tailed tests.

3. It is valid to use the correlation coefficient to describe the relationship between major and working-status of a group of college students

4. If we decrease the Type 1 error rate, the Type 2 error rate will increase (given the same sample)

5. As the value of correlation coefficent (r) gets closer to -1, the x and y become more strongly correlated

Answer 1

Answer #1

1) False, type 2 error is accepting false null hypothesis

2) true

3) false, as they are qualitative variables

4) true

5) true

Answer 2
