Suppose that you expect college freshmen who live on campus will do better academically than those who do not. You select a random sample of 75 freshmen, group them according to where they live, and calculate the following summary statistics. Do these results support your expectations? Assume that the true population standard deviations are equal. Use α = 0.10. Use α = 0.05. What is the p-value of this test?

This assignment is worth 1 points. The extra point will be added to your overall course grade. For example: if you receive an 88% in the course you can receive up to 1 point giving you a new score of 89%. The following rubric will be used. 0.25 point for drawing the normal distribution curve with the mean value labeled on the curve and the appropriate area shaded. 0.25 point for determining the value of the standard deviation of the sample mean. 0.5 point for finding the correct probability. All work must be shown in order to receive any credit. Please upload your completed assignment here. The length of time taken on the SAT for a group of students is normally distributed with a mean of 2.5 hours and a standard deviation of 0.25 hours. A sample size of n = 60 is drawn randomly from the population. Find the probability that the sample mean is between two hours and three hours.
