Question #1 Look at the example on page 71 (slide 28) of the course packet, about Armani Pizza. The coefficient of determination is .928074693 = 0.928074693 , the standard error of the estimate is 28.13339035 = 28.13339035 , the estimated slope coefficient is 10.89424753 = 10.89424753 , the corresponding measured test statistic of a two-tail test on the significance of the slope parameter is 10.16004421 = 10.16004421 . After looking at the p-value corresponding to this test statistic, your conclusion is that the slope is different than zero, the model is useful. You received a raw score of 100% on this question.
