You are required to calculate the correlation between rats' weight (in grams) and their running speed (in seconds). The correlation was +.46. The means and standard deviations necessary for prediction are as follows:

a. What is the equation for predicting running speed in seconds (Y) from weight (X)?
b. What is the expected running speed in seconds for a rat that weighs 290 g?
For Information: Exercise 6 in Module 35.

Weight (X) Running Speed (Y) M 292.90 s,-10.04 (using/n-1) M, 25.20 s, 1.75 (using/n 1)
