Question: 1. An instructor measured quiz scores and the number of hours studying among a sample of 20 college students. If SSxY = 43, SSx = 99, My= 6, and Mx = 5, then what is the regression equation for this sample?

2. A team of clinical psychologists tested the extent to which levels of cognitive functioning were related to the number of symptoms for some disorder expressed in 15 patients. The researchers recorded the following values: SSxy = 48.60, SSx = 355.73, and SSY = 96.40.

(a) What is the proportion of variance, r, in symptoms ( Y) that can be explained by levels of cognitive functioning (X)?

(b) If the total variation in Y is 96.40 (SSY = 96.40), then what is the ss regression or the amount of variation that is predicted by X?
