A regression was run to determine if there is a relationship between hours of TV watched per day (x) and number of situps a person can do (y). The results of the regression were: + -1.068 b-23.461 2-0.571536 -0.756 ne27 Use this to predict the number of situps a person who watches 4.5 hours of TV can do to one decimal place) Direction Hoint Suppose that you run a correlation and find the correlation coefficient is 0.371 and the regression equation is j = 3.9x + 2.23. The mean of your x-values was 5.3. The mean of your y-values was 23.4. If the critical value is .497, use the appropriate method to predict the y value when x is 2.3
