Which of the following options best describes the relationships between the mean, median, and mode of the data? 2010 Winter Olympics Gold Medal Wins by Top 20 Medal-Winning Countries х х х 3 6 7 10 11 12 13 14 Number of gold medals won The mode is less than the median, and the median is less than the mean. The mode is less than the mean, and the mean is less than the median. The mode is greater than the mean, and the mean is greater than the median. The mode is greater than the median, and the median is greater than the mean. The mean, median, and mode are all the same.

I. Background The Food and Drug Administration (FDA) tries to find out whether there is a relation between the number of years people smoked and the percentage of lung damage. FDA asks you for your help to find it out. You interviewed twenty people who have smoked and obtained the following data. II. Technical report: a) Draw a scatter plot. b) Based on the scatter plot, explain whether the number of years and the percentage of lung damage are correlated. If they are correlated, discuss the strength of correlation, and the direction (positive or negative). c) Find the correlation coefficient r. Explain what r implies. d) Choose your own significance level a (1 suggests 0.1, 0.05 or 0.01). State and test the hypothesis. Explain what your findings mean. e) Do your observations in part (b) agree to the results from part (c) and (d)? Explain f) Find the regression line equation. Explain what the line implies. g) Draw the regression line on your scatter plot. h) A man has…
