Suppose that a regression relationship is given by the following:Y = β0 + β1X1 + β2X2 + εIf the simple linear regression of Y on X1 is estimated from a sample of n observations, the resulting slope estimate is generally biased for β1. However, in the special case where the sample correlation between X1 and X2 is 0, this will not be so. In fact, in that case the same estimate results whether or not X2 is included in the regression equation.a. Explain verbally why this statement is true.b. Show algebraically that this statement is true.

The equation of the regression line between two variables x (independent variable) and y (dependent variable) is given by y^=−3x+2; and the correlation coefficient is r=−.95. The possible x-values range from 1 to 10. Based on the given r, which of the following conclusions may be made? x and y are moderately correlated, and y tends to increase as x is increased. x and y are strongly correlated, and y tends to increase as x is increased. x and y are very weakly correlated. x and y are strongly correlated, and y tends to increase as x is decreased. There is no way to tell the relationship between x and y.
8)Suppose that Y is normal and we have three explanatory unknowns which are also normal, and we have an independent random sample of 11 members of the population, where for each member, the value of Y as well as the values of the three explanatory unknowns were observed. The data is entered into a computer using linear regression software and the output summary tells us that R-square is 0.86, the linear model coefficient of the first explanatory unknown is 7 with standard error estimate 2.5, the coefficient for the second explanatory unknown is 11 with standard error 2, and the coefficient for the third explanatory unknown is 15 with standard error 4. The regression intercept is reported as 28. The sum of squares in regression (SSR) is reported as 86000 and the sum of squared errors (SSE) is 14000.
