You will also need the number of males and the number of females in the dataset. You can actually count these in the dataset. Then use the Week 5 spreadsheet to calculate the following confidence intervals. The male confidence interval would be one calculation in the spreadsheet and the females would be a second calculation. 1. Give and interpret the 95% confidence intervals for males an_d a second 95% confidence interval for females on the SLEEP variable. Which is wider and why? 1. Give and interpret the 99% confidence intervals for males an_d a second 99% confidence interval for females on the SLEEP variable. Which is wider and why? We need to find the confidence interval for the SHOE SIZE variable. To do this, we need to find the mean and standard deviation with the Week 1 spreadsheet. Then we can the Week 5 spreadsheet to find the condence interval. This does not need to be separated by males and females, rather one interval for the entire data set. First, find the mean and standard deviation by copying the SHOE SIZE variable and pasting it into the Week 1 spreadsheet. Write down the mean and the sample standard
