2.1. For each of the following, look up the appropriate critical value for either an ANOVA or F test for equality of variance. Use the appropriate table provided to you on Blackboard or use one available in the online text book of your choice. Hint: The first d.f. is for the numerator, and the second is for the denominator. (4 marks) A. F a =0.01(1), 4, 24 B. F a = 0.05(1), 6, 60 C. F a = 0.05(1), 3, 28 D. Fa = 0.025(1), 6, 30 2.2. A biology researcher is attempting to determine whether there are any differences in inter-orbital width among sparrow populations. She conducted an ANOVA test at the a = 0.05 significance level, but the computer program has a defect and it only prints out part of the ANOVA table, as follows: ANOVA Source of Variation SS df MS F Between Groups 0.009348 Within Groups 54 Total 0.083458 60 a. Fill in the missing information in the ANOVA Table above. (5 marks) b. Determine the critical F value needed to interpret the results of this ANOVA (1 mark). c. How many sparrow populations were sampled? ( 1 mark). d. Do these results suggest that a significant difference exist between any of the populations (1 mark)
