Alumni Contributions The director of an alumni association for a small college wants to determine whether there is any type of relationship between the amount of an alumnus's contribution (in dollars) and the number of years the alumnus has been out of school. The data follow. The regression line equation is y' = 280.093 -27.430x. The correlation coefficient is r = -0.883. Compute the standard error of the estimate rounded to at least two decimal places, if appropriate. Assume a = 0.05.
