3. Suppose that one wishes to see whether aspirin and a buffered product are equally effective in alleviating symptoms accompanying influenza. Length of time (in minutes) from taking the drug to patient's saying that they are feeling better is recorded as follows: (To Assume unequal variances) Summary Stats Aspirin Buffered Product n 10 20 15.2 13.4 Co 8.7 6.9 (a) Are the two treatment groups, aspirin and buffered product, independent or de- pendent and why? (b) State the null and alternative hypothesis in symbols. (c) Provide all information needed in the problem to complete the remaining steps including degrees of freedom and significance level. (d) Compute the test statistic (e) Use R to find the p-value and draw the region that supports the p-value (f) Make a conclusion in the context of the problem (g) Create a 95% confidence interval for the difference. Based on the confidence interval only (do not use p-value here) what is your conclusion on a difference
