Question

1. An estimator is consistent if, as the sample size decreases,the value of the estimator approaches the value of the parameterestimated. ____ T/F  

2. For a specific confidence interval, the larger the samplesize, the smaller the maximum error of estimate will be._____   T/F   

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

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

5. a is the measure of the area under the curve of thestandard score that lies in the rejection region for the nullhypothesis. ___ T/F  

6. Rejection of a null hypothesis that is false is a TypeII error. ____ T/F  

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