1, As a result of running a simple regression on a data set, the following estimated regression equation was obtained:

      = 1.6 − 3.0x

Furthermore, it is known that SSR = 674, and SSE = 128.

Calculate the correlation coefficient R ; round your answer to three decimal places.

2.

A sample of data with n = 22 observations is used to run a multiple regression with 8 independent variables.
If this data set has SST = 2309.1068 and SSE = 628.5356, what is the value of the F-statistic for the test of overall significance of this regression relationship?
