Given below are seven observations collected in a regression study on two variables, x (independent variable) and y (dependent variable). x y 2 12 3 9 6 8 7 7 8 6 7 5 9 2 Given the followings b1 = -1.13 SSR = 50.625 SSE= 9.376 Sb1 = .2165 a. At 95% confidence, perform a t test and determine whether or not the slope is significantly different from zero.

A sample of 10 observations collected in a regression study on three variables, x_1(independent variable), x_2(independent variable and y(dependent variable). The sample resulted in the following data. SSR=28, SST=34 Using a 0.01 level of significance, we conclude that the regression model is significant overall. (Enter 1 if the conclusion is correct. Enter 0 if the conclusion is wrong.)
