A scatter diagram is given with one of the points drawn in blue. In addition, two least-squares regression lines are drawn. The line drawn in red is the least-squares regression line with the point in blue excluded. The line drawn in blue is the least-squares regression line with the point in blue included. Onthe basis of these graphs, do you think the point in blue is influential?Does the point in blue seem to be influential?O A. No, because the observation significantly affects the least-squares regression line's slope and/or y-interceptor the value of the correlation coefficient.OB. Yes, because the observation significantly affects the least-squares regression line's slope and/or y-intercept or the value of the correlation coefficient.O C. No. because the observation does not significantly affect the least-squares regression line's slope and/or y-intercept or the value of the correlation coefficient.O D. Yes, because the observation does not significantly affect the least-squares regression line's slope and/or y-intercept or the value of the correlation coefficient.10-10ExplanatoryOK15

The least-squares regression equation is y=784.6x+12,431 where y is the median income and x is the percentage of 25 years and older with at least a bachelor's degree in the region. The scatter diagram indicates a linear relation between the two variables with a correlation coefficient of 0.7962. In a particular region, 26.5 percent of adults 25 years and older have at least a bachelor's degree. The median income in this region is $29,889. Is this income higher or lower than what you would expect? Why?
