Question

1. If z (obtained) is outside of the critical region then the researcher would typically? a. Reject the null hypothesis b. Not reject the null hypothesis c. Modify the weight of the outliers d.Decrease the sample size

2.Assuming that the null hypothesis states that the defendant is innocent, if the defendant is found guilty when actually innocent would exemplify a a. Standard error b. Standard deviation c. Type I error d. Type II error

3.Z (obtained) is the _____. a. Test that determines the sampling distribution b. Test statistic computed in step four of the hypothesis process c. Score that marks the beginning of the critical region d. Score that marks the mean

4.Z (critical) is the _____. a. Test statistic computed in step four of the hypothesis process b. Score that marks the mean c. Score that marks the beginning of the critical region d. Test that determines the sampling distribution

5. The critical region is the area _______. a. Beyond the obtained value b. Between the mean and the obtained value c. Between the mean and the critical value d. Beyond the critical value

Answer 1

1. If the obtained standardized test-statistic is outside the critical region then the researcher should reject the null hypothesis.

2. If the null hypothesis states that the defendant is innocent, if the defendant is found guilty when actually innocent, then we reject the null hypothesis when the null hypothesis is True. It is an example of Type I error.

3. Z (obtained) is the test statistic computed in step four of the hypothesis process.

4. Z (critical) is the score that marks the beginning of the critical region.

5. The critical region is the area beyond the critical value.
