1. What is the average salary in the SalesSalary data set for people with low experience? Answer to the nearest dollar but do not include a dollar sign in your answer.

2. Conduct ANOVA to test the hypothesis that the average salaries are the same for all levels of experience using the SalesSalary data set. What is MSE? Answer to the nearest whole number.

3. Conduct ANOVA to test the hypothesis that the average salaries are the same for all levels of experience using the SalesSalary data set. What is the value of the test statistic? Answer to two decimal places.

4. Conduct ANOVA to test the hypothesis that the average salaries are the same for all levels of experience using the SalesSalary data set. What is the critical value when alpha=.05? Answer to two decimal places.

5. Using the SalesSalary data test the null hypothesis that the average salaries are the same for all levels of experience. Conduct this test at the .05 level of significance.a. Fail to reject the null hypothesis because the test statistic is greater than the critical value

b. Fail to reject the null hypothesis because the test statistic is less than the critical value.

c. Reject the null hypothesis because the test statistic is greater than the critical value.

d. Reject the null hypothesis because the test statistic is less than the critical value.

6. Using the SalesSalary data you reject the null hypothesis that the average salaries are equal for all experience levels at the .001 level of significance.a. True

b. False

7. Consider the ANOVA table here. What is MSTR? Answer to two decimal places.8. Consider the ANOVA table here. What is the total sum of squares? Answer to two decimal places.9. Consider the ANOVA table here. What is the p-value? Answer to three decimal places.

10. Consider the ANOVA table here. How many observations were there in this data set?

11. Suppose there are 3 numerator degrees of freedom and 15 denominator degrees of freedom. What is the critical F value for a .05 level of significance test? Answer to two decimal places.

12. Suppose there are 4 treatments and each one has 6 observations. You are using the data to conduct ANOVA. What is the critical F value for a .05 level of significance test? Answer to two decimal places.

13. For the ANOVA output below certain fields are missing. What is the total sum of squares (round to the nearest whole number)?

14. For the ANOVA output below certain fields are missing. How many degrees of freedom are there for the denominator in the F statistic?

15. For the ANOVA output below certain fields are missing. What is MSTR (answer to one decimal point)?

16. For the ANOVA output below certain fields are missing. What is MSE (answer to one decimal point)?

17Consider the ANOVA table in the previous question where SSTR is 284.4. Because 1.6476<3.806 you fail to reject the hypothesis the that population means of the groups are equal.

a. true

b. false
