For each variable of interest, do the following: 1. Find the mean, five-number summary, range, variance, and standard deviation. Display these numbers in a format that is easy to understand. 2. For each variable of interest, use its five-number summary to construct a boxplot. Each boxplot must be constructed horizontally, and must be accompanied by a brief descriptive paragraph that assesses whether the data appear to be symmetrical, left-skewed, or right-skewed. Construct a 95% confidence interval for the mean μ...
