ani Echange in 2 regardless of the value of 1 A multiple tue b) false 1.6OThe valas of MSE is 212 a) trueb) false 42· The test statistic F fouad in the ANOVA tubde for testing the wsefulness of the regression moxdel is Total SS/SSE egression model involving 40 observations, the following estimated regression model was calculated by a MSE/MSR b. MSR/MSE SSR/SSE SSEI SSR 43, 134, +62, 8, For this mendel, the fotlowing staisnics are sven SSR-501 and ssE =99. Then, the value of MSR ie a. 12.525 b.33 . 18.52 44Ifyou wish to estimate the difference between two population means when the population variances are known the 9 % confidence interval estimate can be developed us ng which of the following critical values of z? a. 1.64 b. 2.575 e.2.325 d. 1.275e2582 45. One-way ANOVA is used when: a. b. c. d. analyzing the difference between more than two population means analyzing the difference between two population variances analyzing the difference between two sample means analyzing the difference between two population proportions mone of these e. 46. In one-way ANOVA, suppose that there are three treatments with nis, n2-6 and n3o5 . Then the rejection region for this test at the 5% level of significance is: a. F >3.24 b.F>4.08 c.F>3.63 d. F>3.68 e.F>3.22 47. In one-way ANOVA test, the test statistic is F-425. The rejection region is F-306 for the 5% level of significance, F > 3.8 for the 2.5% level, and F > 4.89 for the 1% level. For this test, the approximate p- value is: c. between 0.01 and 0.025 a. greater than 0.05 b. between 0.025 and 0.05 d. approximately 0.05 e. approximately 0.0Explanation / Answer
Q 39 degrees of freedom = n-2 = 10-2 =8, the critical value of t for 8 df at 5% level of significance is 2.306
Answer: Option C) 2.306
Q 40 Answer: True
Q 41 SST = 2000, SSR = 1608, therefore SSE = SST-SSR = 2000 -1608 = 392
N = 40, k = 4,
df for Error term is = N-k-1 = 40-4-1 = 35
MSE = SSE/df = 392/35 = 11.2
Answer: False
Q 42 Answer: Option b) MSR/MSE
