Consider the following regression results based on 20 observations. (You may find it useful lo reference the t table.) Coefficients 33.8605 Standard Error 4.4081 t Stat 7.681 p-value 0.000 Intercept X1 0.3634 0.1204 3.018 0.007 po a-1. Choose the hypotheses to determine if the intercept differs from zero. Ho: Bo 0; HA: Bo < 0 - 0: HA: Bo0 ces O Ho1 Po s 0; HAI Bo > 0 a-2. At the 5% significance level, what is the conclusion to the hypothesis test? Does the intercept differ from zero? O Reject Ho; the intercept is greater than zero. Reject Ho: the intercept differs from zero. O Do not reject Ho, the intercept is greater than zero. O Do not reject Ho: the intercept differs from zero. b-1. Construct the 95% confidence interval for the slope coefficient. (Negative values should be indicated by a minus sign. Round final answers to 2 decimal places.) Confidence interval to b-2. At the 5% significance level, can we conclude the slope differs from zero? O No, since the interval does not contain zero. O No, since the interval contains zero. O Yes, since the interval does not contain zero. O Yes, since the interval contains zero. Consider the following regression results based on 20 observations.
