he fish in my pond have mean length 14 inches with a standard deviation of 2 inches and mean weight 4 pounds with a standard deviation of .8 pounds.  The correlation coefficient of length and weight is .7.  If the length of a particular randomly selected fish is reported to be 17 inches, and if we use simple linear regression to predict the weight of a fish whose length is reported to be 15.8 inches long, then what is the expected squared error?
