Adrug company is testing out two new possible treatments for high cholesterol. 15 patients, all of whom started with cholesterol levels between 200 and 220 are enrolled in an initial study. 5 of the pațients are assigned to the control group and will receive a placebo treatment, 5 more will receive experimental drug A, and the remaining 5 will receive experimental drug B. All assignment to groups was done randomly. After following these patients for 6 weeks on the drugs, their cholesterol levels were measured again yielding the following results: Placebo Treatment A Treatment B 184 191 195 |178 192 188 Reference Number 193 187 187 187 186 |188 188 185 186 190 195 188.8 1 2 4 Мean Test the null hypothesis that the means of all the groups (i.e., placebo, treatment A, and treatment B) are the same versus the alternative hypothesis that there is some difference between the groups. Perform the test at the alpha = 0.05 level. What is the p-value and conclusion of this test? p-value = 0.045; Fail to reject the null p-value = 0.045; Reject the null p-value = 0.956; Fail to reject the null p-value = 0.956; Reject the null
