In this assignment students will demonstrate their understanding of the distribution of means doing all steps of hypothesis testing. For each problem students will write out all steps of hypothesis testing: 1. State the null and research hypotheses. 2. Set the level of risk associated with the null hypothesis. 3. Select the appropriate test statistic. 4. Compute the test statistic value (called the obtained value). 5. Determine the value needed for rejection of the null hypothesis using the appropriate table of critical values for the particular statistic. 6. Compare the obtained value and the critical value. 7. Make your decision. After completing of the steps of hypothesis tests, write out your results in APA format and in easy-to-understand language. 4. The average age for licensed drivers in a county is 43.4, with a standard deviation of 16, and the distribution is approximately normal. A county police officer was interested in whether the average age of those receiving speeding tickets is less that the average age of the population who has a license. She obtained a sample of 23 drivers with speeding tickets. The average age for this sample was 33.4. Do all the steps of hypothesis testing using the 0.01 significance level.

Question

In this assignment students will demonstrate their understanding of the distribution of means doing all steps of hypothesis testing.

For each problem students will write out all steps of hypothesis testing:

1. State the null and research hypotheses.

2. Set the level of risk associated with the null hypothesis.

3. Select the appropriate test statistic.

4. Compute the test statistic value (called the obtained value).

5. Determine the value needed for rejection of the null hypothesis using the appropriate table of critical values for the particular statistic.

6. Compare the obtained value and the critical value.

7. Make your decision.

After completing of the steps of hypothesis tests, write out your results in APA format and in easy-to-understand language.

4. The average age for licensed drivers in a county is 43.4, with a standard deviation of 16, and the distribution is approximately normal. A county police officer was interested in whether the average age of those receiving speeding tickets is less that the average age of the population who has a license. She obtained a sample of 23 drivers with speeding tickets. The average age for this sample was 33.4. Do all the steps of hypothesis testing using the 0.01 significance level.
