is it possible for me to get an answer for these questions?

3. (15 points) A recent study asked college students to indicate their level of alcohol use, and in this problem, we compare the group of students who said they were light drinkers to the group of students who said they were heavy drinkers. Each student was also given several cognitive skills tests and assigned a cognition score (scores range from -5 to 5) based on their performance on these tests. The 83 students who said they were light drinkers had a mean cognition score of 0.1302 with a standard deviation of 0.75, while the 16 students who said they were heavy drinkers had a mean cognition score of -0.2338 with a standard deviation of 0.65. Test to see if there is evidence that heavy drinkers have a lower mean cognitive level than light drinkers. Let pi = the mean cognition score for students who are heavy drinkers, and #2 = the mean cognition score for students who are light drinkers. (a) State appropriate hypotheses to test whether heavy drinkers have a lower mean cognitive level than light drinkers. Ho : Ha : (b) Calculate the test statistic. Use four decimal places. (c) To find the p-value for the test statistic, we use a t-model with of = Using StatKey, the p-value = Shade the appropriate region on the t-distribution curve below. (d) Decision (Encircle one): "Reject Ho" or "Do not reject Ho" (Use a = .05.)(e) Write a conclusion to your hypothesis test in context. (f) Can we conclude from this study that heavy drinking affects cognitive ability? Why or why not
