For a biology project John measured the length( inches) and weight(ounces) of 50 snakes of the same variety. John calculated also the correlation coefficient r and he founf=d it to be r=0.4

Suppose that John found that mean length was 33 inches and the standard deviation was 4 inches. However, after he did all his calculations he found out that he used a measuring tape that was faulty. His tape was 10% longer than it should have been. In other words when John measured 1.1 inches the true length was 1 inches.

1, calculate the true mean and standard deviation of the snakes.

2, calculate the true correlation coefficient r
