A sample of 6 observations collected in a linear 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=72, SST=88Calculate the F test statistics to determine whether a statistically linear relationship exists between x and y.A sample of 12 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=60, SST=86Calculate an unbiased estimate of the variance of the error term epsilon.
