Plase solve. (a) contrast the shapes of the data sets displayed in the box-and-whisker plots in question 1. explain what the difference in the shapes means in context of the situation. (b) compare the spread of the data sets. discuss both the overall spread and the spread within the boxes. (c) use an appropriate measure of central tendency to compare the center of the data sets. explain what the difference in those measures means in context of the situation.

Data from 2005 for various age groups show that for each $100 increase in the median weekly income for whites, the median weekly income of blacks increases by $105. also, for workers of ages 25 to 54 the median weekly income for whites was $676 and for blacks was $527. (a) let w represent the median weekly income for whites and b the median weekly income for blacks, and write the equation of the line that gives b as a linear function of w. b = (b) when the median weekly income for whites is $760, what does the equation in (a) predict for the median weekly income for blacks?
