Use the following two-way ANOVA tableSourceABA*BErrorTotalSS2.250.951.202.16.5CO31623MS0.750.950.301313What would be the best decision for a hypothesis test to see if there is a difference in the levels of Factor A? For a significance level of 0.05 and d.f. 3 and 16, the critical value is 3.239.O a. Reject the null hypothesis, the F-test statistic was greater than the critical value.O b. Fail to reject the null hypothesis, the F-test statistic was greater than the critical value.O c. Fail to reject the null hypothesis, the F-test statistic was less than the critical value.O d. Reject the null hypothesis, the F-test statistic was less than the critical value.

Given below are the analysis of variance (ANOVA) results from a Minitab display. Assume that you want to use a 0.01 significance level in testing the null hypothesis that the samples come from populations with the same mean.

(circle one) Reject H0 since the p-value is greater than the significance level. Fail to reject H0 since the p-value is greater than the significance level. Reject H0 since the p-value is less than the significance level. Fail to reject H0 since the p-value is less than the significance level.

Choose the appropriate statistical test. When computing, be sure to round each answer as indicated. A dentist wonders if depression affects ratings of tooth pain. In the general population, using a scale of 1-10 with higher values indicating more pain, the average pain rating for patients with toothaches is 6.8. A sample of 30 patients that show high levels of depression have an average pain rating of 7.1 (variance 0.8). What should the dentist determine? 1. Calculate the estimated standard error. (round to 3 decimals). [st.error] 2. What is thet-obtained? (round to 3 decimals). 3. What is the t-cv? (exact value) 4. What is your conclusion? Only type "Reject" or Retain"
