(Requires technology.) In Section 2.10 we examined the percentage of adult smokers. Here we break out smokers by sexthe percentage of males who smoke and the percentage of females who smoke. If you are male, use only the male data; if you are female, only the female data. a. Construct a scatter plot of the percentage of smokers of your sex. b. On your graph sketch a best-fit line. By estimating coordinates of points on your best-fit line, calculate the slope of the line. What does this tell you? c. Reinitialize your data by setting 1965 as year 0. Now use technology to generate a linear regression line and correlation coefficient (cc) to your new data set. Record the equation and the cc. How good a fit is the regression line to the data? What does the vertical intercept tell you? The slope? d. Write a 60-second summary about the smoking trends for your sex. If possible, compare your results to those of someone of the opposite sex.
