Refer to the following partial anova results from excel (some information is missing).

Question 1 Refer to the following partial ANOVA results from Excel (some information is missing). Picture  The number of observations in the entire sample is Answer 20 19 22 1 points  Question 2 Here is an Excel ANOVA table that summarizes the results of an experiment to assess the effects of ambient noise level and plant location on worker productivity. The test used a= 0.05. Picture  Is the effect of plant location significant at a= .05? Answer Yes No Need more information to say 1 points  Question 3 Using one-factor ANOVA with 30 observations we find at a= .05 that we cannot reject the null hypothesis of equal means. We increase the sample size from 30 observations to 60 observations and obtain the same value for the sample F test statistic. Which is correct? Answer We might now be able to reject the null hypothesis We surely must reject H0 for 60 observations C.We cannot reject H0 since we obtained the same F-value It is impossible to get the same F-value for n = 60 as for n = 30 1 points  Question 4 What are the degrees of freedom for Tukey's test statistic for a one-factor ANOVA with with n1= 6, n2 = 6, n3 = 6? Answer 3, 6 6, 3 6, 15 3, 15 1 points  Question 5 The Internal Revenue Service wishes to study the time required to process tax returns in three regional centers. A random sample of three tax returns is chosen from each of three centers. The time (in days) required to process each return is recorded as shown below Picture  The test to use to compare the means would require Answer Three-factor ANOVA One-factor ANOVA Two-factor ANOVA without replication Two-factor ANOVA with replication 1 points  Question 6 Here is an Excel ANOVA table that summarizes the results of an experiment to assess the effects of ambient noise level and plant location on worker productivity. The test used a= 0.05. Picture  Is the effect of noise level significant at a= .01? Answer Yes No Need more information to say 1 points  Question 7 Refer to the following MegaStat output (some information is missing). The sample size was n = 65 in a one-factor ANOVA. Picture  At a = .05, which is the critical value of the test statistic for a two-tailed test for a significant difference in means that are to be compared simultaneously? Note: this question requires a Tukey table. Answer 2.81 2.54 2.33 1.96 1 points  Question 8 Refer to the following partial ANOVA results from Excel (some information is missing). The response variable was Y = maximum amount of water pumped from wells (gallons per minute). Picture  The MS for interaction is Answer 7.25 8.17 8.37 9.28 1 points  Question 9 Refer to the following partial ANOVA results from Excel (some information is missing).  ANOVA Table Picture  The number of observations in the original sample was Answer 59 60 58 54 1 points  Question 10 To compare the cost of three shipping methods, a random sample of four shipments is taken for each of three firms. The average cost per shipment is shown below. Picture  In a one-factor ANOVA, degrees of freedom for the within-groups sum of squares will be Answer 11 3 9 2 1 points  Question 11 Which is the Excel function to find the right-tail p-value for Fcalc = 4.52 with n1 = 15, n2 = 12? Answer =FDIST(4.52, 15, 12) =FINV(4.52, 14, 11) =FDIST(4.52, 14, 11)

=FINV(4.52, 15, 12)
