Question: In a study of the Mormon cricket (Anabrus simplex), the correlation between female body weight and ovary weight was found to be r = 0.836.

In a study of the Mormon cricket (Anabrus simplex), the correlation between female body weight and ovary weight was found to be r = 0.836. The standard deviation of the ovary weights of the crickets was 0.429 g. Assuming that the linear model is applicable, estimate the standard deviation of ovary weights of crickets whose body weight is 4 g.33
