# T/F, Multiple choice-Estimation, Hypothesis

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?

#### Solution Preview

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

Answer: True

Standard error is inversely proportional to the square root of sample size.

2. An estimator is consistent if, as the sample size decreases, the value of the estimator approaches the value of the ...
