Continued from previous. For a certain population, a health and nutrition survey finds that: the average weight is 175 pounds with a standard deviation of 42 pounds, the average height is 67 inches with a standard deviation of 3 inches, and the correlation coefficient is 0.7. Furthermore, the scatterplot of height on weight is an oval-shaped cloud of points. Use regression to estimate the average weight of people six feet tall in this population at the time of the survey: pounds Provide a give-or-take value for this estimate; that is, compute the r. m.s.-error: pounds
