QUESTION 33 Use the output provided in the formula sheets folder. Using the reduced model, what is the value of S (standard deviation)? 0 0.30 O 2.85 O S? O 221.2 QUESTION 34 Use the output provided in the formula sheets folder. Using the reduced model, test if X2 is significant to the model. What is your test statistic for this test? (i.e. Tcal = ?) O 0.80 O -1.21 O 3.42 O -0.97QUESTION 35 Use the output provided in the formula sheets folder. For the test in the previous question, if a = 0.05 what is your critical value? (what is the value from the t-table for this test?) O 3.578 O 4.303 O 2.262 O 2.365QUESTION 36 Use the output provided in the formula sheets folder. Using the full model, test if the model is useful using an analysis of variance F-test. What is your conclusion at a = 0.05? O Do not reject Ho: there is evidence the model is useful O Reject Ho: there is evidence the model is useful O Do not reject Ho: there is not evidence the model is useful O Reject Ho: there is not evidence the model is not usefulQUESTION 37 Use the output provided in the formula sheets folder. Using the full model, find a 95% confidence interval for $2. O (-0.155, 0.237) O (-32.075, 52.315) O (-4.322, 8.574) O (-8.668, 10.514)QUESTION 38 Use the output provided in the formula sheets folder. Using the full model: looking at the p-values, which variables are significant at an alpha of o = 0.05? O X1 and X2 O None O X1, X12, and X1X2 OX2QUESTION 39 Use a partial F to test if the squared terms and the interaction term are significant to the model when taken together. What is the value of F*? (what is your calculated partial F*) O 1.225 O 0.623 O 4.93 O 10.4QUESTION 40 Use the output provided in the formula sheet folder. What is your null hypothesis for the testjn question 39? O H013=|34=|35=0 0 H01 e = D 0 Ha I 31 = I32 = 0 O Ho=1=l32=3=l34=s=0
