Indicate whether the following statement is true or false

a) If the hypothesis Hsub0:Betasub1=0 is rejected,then it can be safely concluded that x causes y.

b)Suppose a regression of y on x is run and the t statstic for testing Hsub0: Betasub1=0 versus Hsuba:Betasub1 not equal to 0

has a p value of 0.0295 assosiated with it. Using a 5% level of significance, the null hypothesis should be rejected.

c)If the correlation between y and x is 0.9, then the R^2 value for a regression of y on x is 90%.

d)As long as the R^2 value is high for an estimated regression equation , it is safe to use the equation to predict for any value of x.

e)If the R^2 value for regression of y on x is 75%. then the R^2 value for a regression of x on y is also 75%.
