10. The heights of 500 female students are measured, half of whom are college students and half of whom are second-grade students. How many modes would you expect for this distribution? Why? Would this distribution be symmetric, left-skewed, right-skewed or none of these? Why? 11. The following table lists costs of a pizza slice and cost of subway fare over a 50 year period. Construct a scatterplot of pizza cost and subway fare. Does there appear to be a correlation? Find the line of best fit with pizza cost on the x-axis, subway fare on the y-axis. Using the correlation coefficient r, decide if there is a strong, weak or no correlation and in what direction if there is correlation? Using the line equation predict the cost of subway fares in 2020 if a pizza costs $3. How much did a pizza slice cost when the subway fare was 0.65? Where would this mathematical model not make sense?
