HI, I need help on these stats questions:

Section 3 Questions 10, 11, 12, 13 and 14 are based on the following set-up. Question 9 provides the random input values for digits indicated as A, B, C. A pharmaceutical company tested three formulations of a pain relief medicine for migraine headache sufferers. For the experiment, 27 volunteers were selected and 9 were assigned to one of three drug formulations. The subjects were instructed to take the drug during their next migraine headache episode and to report their pain on a scale of 1=no pain to 10= extreme pain. The data are given below: Drug A Drug B Drug C 4 5 A E 3 2 4 3 4 U'lU'lChU'l'dO'O'dO' Question 9 (0.01 points) '1 Saved The following list of numbers provides the random inputs required for questions in this section. Select the option with the answer "1" to continue. OA}3 Question 10 (2 points) Which of the following statement(s) islare true? You must select all true statements to get marks. C] A} The largest within-group-standard deviation is less than twice the smallest within-group-standard deviation. C] B) Based on the Anderson Darling test of normality we can reject the hypothesis that the residuals of the One-Way ANOVA model have normal distribution at 5 percent signicance level. C] C) There is a linear relationship between the drug type and pain level. C] D) Drug type and pain level are both quantitative variables. Question 11 (2 points) What's the value of the F-statistic for the One Way ANOVA test for the equality of the means? Question 12 (2 points) What's 5, the estimate of the residual standard deviation for the OneWay ANOVA model? Question 13 (2 points) Which of the following is the correct conclusion of the One-Way ANOVA F test? (A) At 5% significance level, there is significance evidence that all the means are the same. (B) At 5% signifiance level, there is significant evidence that not all the means are the same . O C) At 5 % significance level, there is not enough evidence that all the means are the same ( D) At 5% significance level, there is not enough evidence that not all the means are the same. Question 14 (2 points) Perform a Tukey Multiple comparison procedure to identify the means of which pairs of groups are significantly different at 5% experimentwise significance level? Select all that apply to get marks. A) Drug A and Drug B ( B) Drug A and Drug C ( C) Drug B and Drug C (D) None of the above
