Question 11 1 pts How Much Alcohol Do College Students Drink? According to the website www.collegedrinkingprevention.gov, "About 25 percent of college students report academic consequences of their drinking including missing class, falling behind, doing poorly on exams or papers, and receiving lower grades overall." A statistics student is curious about drinking habits of students at his college. He wants to estimate the mean number of alcoholic drinks consumed each week by students at his college. He plans to use a 90% confidence interval. He surveys a random sample of 71 students. The sample mean is 3.93 alcoholic drinks per week. The sample standard deviation is 3.78 drinks. Let's do some exploration with technology to see how changes in the confidence level affect the confidence interval. Use the applet below to answer the following questions. Central probability = 0.50 -3 -2 -1 0 2 t-score = 0.6750 central probability = 0.50 degrees of freedom = 50central probability = 0.5 degrees of freedom = 50 Answer the following question about this study. Use the applet above, if necessary. Find the critical T-value for this 90% confidence interval. Hint: Use the applet to find the T-value for 90% confidence with df = 71 - 1 = 70. G ( 0 words &gt
