Question

True or False

1. A confidence interval is an example of a point estimate

2. You are 100% confident that a confidence interval for the true population mean includes the sample mean.

3. All else held equal, decreasing variability in a population will cause the length of the confidence interval generated to increase

4. The null hypothesis is the hypothesis that is tested directly

5. Depending on the statement of the original question, the equal sign may be in the null hypothesis or in the alternative hypothesis

6. If you reject the null hypothesis, you could have made a Type 1 correct decision

7. If your sample result match to the hypothesized value then you should accept the null hypothesis.
