a. Given the following Information obtained from four normally distributed populations, construct an ANOVA table. (Round "ss" to 2 decimal places, "MS" to 4 decimal places, and "F' to 3 decimal places.) SST = 66.03; SSTR = 18.89; c = 4; n1 = n2 = n3 = n4 = 15 ANOVA Source of Variation SS off MS F p-value Between Groups 18.89 6.2967 7.480 0.000 Within Groups 47.14 0.8418 Total 66.0 59 b. At the 10% significance level, what is the conclusion to the ANOVA test of mean differences? O Reject He; we can conclude that some means differ. Do not reject Ho; we cannot conclude that some means differ. O Do not reject Ho; we can conclude that some means differ. Reject He; we cannot conclude that some means differ.
