EARNINGS = beta0 + beta1 * HEIGHT + error where the unit of EARNINGS is dollars per year and the unit of HEIGHT is inches. Answer the following questions: What is the effect of increasing HEIGHT by 10 inches on annual earnings? Earnings change by How much do you predict the annual earnings to be for a man that is 67 inches tall? Is the variable HEIGHT statistically significant at 5%? (type YES or NO) Construct a 90% confidence interval for the slope coefficient of HEIGHT: between Calculate the test statistic for the null hypothesis H0: beta1 <= 0 against the alternative H1: beta1 > 0: t = What is the p-value for the null hypothesis that H0: beta1 <= 0 against the alternative that H1: beta1 > 0? (if the pvalue is smaller than 0.01 type 0.00) Test the one-sided hypothesis that H0: beta1 <= 0 against H1: beta1 > 0. The t-statistic in this case is REJECT) the null hypothesis HO.
