Part 3 a. Find the mean for percent of low-income working families and percent of 18–64-year-old with no HS diploma. Compare these two means. What do you observe? b. Find the standard deviation for each of these two groups. Which group has the larger variation? c. Construct the boxplots for each group. Attach a copy of the boxplot to the project Is there any outlier for each group? Find the value of Q1 for each group. Which group has the lower value of Q1?
