Aresidual plot is shown. which statements are true about the residual plot and the equation for the line of best fit for the data? check all that apply. 1) the equation for the line of best fit is not a good approximation for the data because the points have a curved pattern. 2) the equation for the line of best fit is a good approximation for the data because the points are random, having no pattern. 3) the residual plot has a linear pattern. 4) the points of the residual plot are spread evenly above and below the x-axis. 5) the residual plot has the pattern of a curve. 6) the equation for the line of best fit is not a good approximation for the data because the points have a linear pattern.

If your score on your next statistics test is converted to a z score, which of these z scores would you prefer: minus2.00, minus1.00, 0, 1.00, 2.00? why? a. the z score of 2.00 is most preferable because it is 2.00 standard deviations above the mean and would correspond to the highest of the five different possible test scores. b. the z score of 0 is most preferable because it corresponds to a test score equal to the mean. c. the z score of minus2.00 is most preferable because it is 2.00 standard deviations below the mean and would correspond to the highest of the five different possible test scores. d. the z score of minus1.00 is most preferable because it is 1.00 standard deviation below the mean and would correspond to an above average
