Suppose that you run a regression of Y, on X, with 110 observations and obtain an estimate for the slope.Your estimate for the standard error of ₁ is 1. You are considering two different hypothesis tests:The first is a one-sided test: Ho: B1-0, Ha: 31>0, a = .05The second is a two-sided test: Ho: 31-0, Ha: B1 0,a = .05(a) What values of , would lead you to reject the null hypothesis in the one-sided test?(b) What values of , would lead you to reject the null hypothesis in the one-sided test?(c) What values of would lead you to reject the mill hypothesis in the one-sided test, but not thetwo-sided test?(d) What values of 3 would lead you to reject the null hypothesis in the two-sided test, but not theone-sided test?

Given that running a regression of Yi on Xi with 110 observations and the estimate for the standard…

For a sample of 48 monthly observations the regression of the percentage return on an investment (y) against the percentage change in the consumer price index (x) was estimated. The sample regression line, obtained through least squares, is shown below. The estimated standard deviation of the slope of the population regression line was 1.8. Test the null hypothesis that the slope of the population regression line is 0 against the alternative that the slope is positive.

The average midterm score in a large statistics class was 60 with an SD of 5. The average final score in the same class was 80 with an SD of 15. The correlation coefficient between midterm and final scores was r=0.6. Using the regression line, we predict the final score of a student with a midterm score of 70 to be but this prediction is likely to be off by about Fill in the blanks, rounding each answer to one decimal point.
