A study examined tumor weights using six different drugs. The data for the groups are in the Excel spreadsheet. Is there a difference between treatment groups? This is a hypothesis test using STATA. Include an output/snapshot from STATA. Summarize the result (as text). Are all groups different? You still have to test assumptions!

Expert Solution

Step 1
Taking the STATA output provided in the image, the p-value for the hypothesis test is 0.0002, and which is less than the significance level of 0.05. This tells us that we can reject the null hypothesis and conclude that there is a significant difference in tumor weights between the treatment groups.
