1. For a specific confidence interval, the larger the sample size, the smaller the maximum error of estimate will be. T

2. An estimator is consistent if, as the sample size decreases, the value of the estimator approaches the value of the parameter estimated. ____ T/F

3. When we reject the null hypothesis, we are certain that the null hypothesis is false. ___ T/F

4. The alternative hypothesis, sometimes referred to as the research hypothesis, is supported by using the sample evidence to contradict the null hypothesis. ___ T/F

5. Rejection of a null hypothesis that is false is a Type II error. ____ T/F

6. Alpha is the measure of the area under the curve of the standard score that lies in the rejection region for the null hypothesis. ___ T/F

7. The maximum error of estimate is controlled by three factors: level of confidence, sample size, and standard deviation. ____ T/F

8. You are constructing a 95% confidence interval using the information: n = 60, = 65.5, s = 2.5, and E = 0.7. What is the value of the middle of the interval?
