D Question 5 3 pts A sample of 28 students participated in an experiment in which each was randomly assigned to one of three emotional states (guilt, anger, neutral). through a reading/writing scale. After the task students were presented with a decision problem where the stated option had predominantly negative features. Prior to making the decision, the researcher asked each subject a list of possible alternatives. The researcher then compared the mean number of alternatives across the three emotional states using a completely randomized design. If MSE = 0.25 and MST-3.4 then the F statistics for the significance of the treatment is equal to The rejection region for the test at alpha 0.05 is equal to . We conclude that there is statistical evidence to support the alternative hypothesis that the means differ. Moreover, the standard error of the model is equal to . Round off ALL your answers to two decimal digits. Previous Next

Explanation / Answer

F-Statistics for the significance of the treatment is equal to 3.4/0.25 = 13.6. The rejection region for the test at alpha 0.05 is equal to 3.3852. We conclude that there is statistical evidence to support the alternative hypothesis that the mean differ. Moreover, the standard error of the model is equal to sqrt(0.25) = 0.5
