Based on the regression results:

(b) What is the estimated regression equation?

(c) How much of the withdraw amount is explained by the regressors?

(d) What is the standard error of the error term in the regression equation?

(e) Are any of the explanatory (independent) variables significant at the 10% level of significance? How do you know?

(f) What is the null and alternative hypothesis that Excel is testing in reporting the t-stats above?

(g) Is the regression equation as a whole significant at the 1% level of significance? How do you know?

(h) What is the predicted withdraw amount if SECONDS = 30 for a female?

(i) What is the predicted withdraw amount if SECONDS = 31 for a female?

(j) What is the predicted withdraw amount if SECONDS = 30 for a male?

(k) What is the marginal impact on withdraw amount of a female spending an additional second at an ATM machine?

(l) What is the marginal impact on withdraw amount of a person being a female (compared to a male) for someone who spends 30 seconds at an ATM machine?

(m) Use the 1% level of significance to test to see if the coefficient of Seconds is different than -3.5.
