Standardized stock price indicators in three different countriesover a week are listed below. An analyst is interested in knowingif the stock markets of these different countries are dependent onone another. The data set and a partial ANOVA table for this studyare provided below.

Compute the MSE andthe F statistic
| | MSE = 374. F =2.22 |
| | MSE = 168.4. F =2.22 |
| | MSE = 2.22. F = 15 |
| | MSE = 2,526. F =2.22 |
| | None of the above Suppose the p-valuefor the test is 0.143. At the 0.05 level of significance, how doyou conclude? | | Do not reject H0.There is no evidence that the means are significantly different | | | Do not reject H0.Evidence exists that the means are significantly different | | | Reject H0. There is noevidence that the means are different | | | Reject H0. P-value isgreater than alpha | | | None Calculate the TukeyCriterion (T) for use in a Tukey pairwise comparisons test. Usealpha of 0.05. | | T = 3.67 | | | T = 19.05 | | | T = 19.44 | | | None of the above |
of the abovestatements is correct Which of the pairs ofsample means are statistically significant? | | Sample means forGroups 1 and 2 | | | Sample means forGroups 1 and 3 | | | Sample means forGroups 2 and 3 | | | None issignificant |
