Sugar consumption is a hot topic when it comes to good nutrition. Twelve-ounce cans of soft drinks often have 10 teaspoons of sugar in them. A random sample of 75 college students were asked how many cans of soft drinks they typically consume on a given day. That number was multiplied by 10 to give a daily amount of sugar (in teaspoons) consumed from soft drinks. The following statistics were calculated.

After once again losing a football game to the college’s arch rival, the alumni association conducted a survey to see if alumni were in favor of firing the coach.  A simple random sample of 200 alumni from the population of all living alumni were surveyed, and 105 of the alumni in the sample were in favor of firing the coach. Please answer the following questions. Be sure to show all calculator input for any partial credit. a.  Find a 90% confidence interval for the true proportion of living alumni who are in favor of firing the coach (please show all calculator input).  (2 points) b.  Verify you meet the conditions to use the interval you found in part (a).  (3 points) c.  Based on the confidence interval found in part (a), can the alumni association claim that the majority of alumni are in favor of firing the coach? Why or why not?  (3 points)
