An educational researcher sought to determine the average number of friends that student on a particular college campus made during their first year of school. Questioning a random sample of 50 students completing their freshmen year, he finds a sample mean of 3 friends and a standard deviation of 1. Separately, construct a 95% confidence interval and a 99% confidence interval to estimate the mean number of friends made by the population of college students during their first year on campus.

A researcher is trying to determine whether there is a difference in the number of new friends that students make during their freshman year based on whether they live on or off campus. The descriptive statistics for the two groups are presented below. Conduct the appropriate hypothesis test to determine whether there is a significant difference in the number of new friends made. On-Campus Freshmen Off-Campus Freshmen X1 = 4.48 s1 =1.81 N1 =16 X2 =3.61 s2 =1.86 N2 =16...
