Discussion:
Q1: Suppose you have drawn a simple random sample of 225 students from OSU. In this sample, 45 students own Blackberries. Let π denote the proportion of OSU students who own Blackberries. Construct a 95% confidence interval for π
Q2: Suppose you have drawn a simple random sample of 100 students from OSU and recorded how much money each student spent on room and board in Fall 2009. For your sample, sample mean (X) is $3500, and sample standard deviation (s) is $1500. Let μ denote the mean of this population. Construct a 95% confidence interval for μ
