D Question 11 2 pts If you have a negative value of the independent-samples t statistic (t-value), you know that O the t-test must be significant. O no need to worry and it's possible to have a negative t-value. O you've made a mistake O you need to calculate t-value again to see if can have a positive result. O p-value must great than 0.05.Question 12 2 pts In t-test, the further the t-value falls from 0, O the more likely it is that the difference is significant. O the less likely it is that the difference is significant. O the more likely then p-value is greater than 0.05 O the more likely the difference is zero. O the more likely the t-value is invalid.Question 13 2 pts A Shapiro-Wilks test was run on two groups of sample data that contain population counts of parrots and toucans in various parks around the world. The test resulted in a p-value of .055 for both groups. What can be concluded about the data? The variances of parrot samples and toucan samples are not the same. Both sample groups are normally distributed. The means of the parrot data and the toucan data are not signicantly different None of the sample groups are normally distributed. Equal variances are assumed for the two sample groups Question 14 2 pts Is there any problem to use multiple t-tests instead of ANOVA to compare multiple groups' means? It increases the probability of making a Type II error Nothing, except it requires more computation than doing a single ANOVA There is no difference between using an ANOVA and using multiple t-tests It's actually better because it makes it easy to reject the null hypothesis It increases the probability of making a Type I error Question 15 2 pts Games-Howell Post Hoc test is used to: O show the descriptive statistic O show if ANOVA can be rejected O identify exactly which groups are significantly different from each other . O see if one mean can predict the other O see if there is a relationship among group meansI] L Question 16 2 pts Which of the following is true about an independent sample one-way ANOVA? Choose all that apply. The F-value would be less than 1 if we have rejected the null hypothesis. The F-value is a ratio of the between groups variance and the within groups variance The F-value is a difference of the mean from each group divided by the standard deviation The p-value is positively associated with the F-value. The F-value would be 1 or very close to 1 if we have failed to reject null hypothesis D Question 17 2 pts If Levene's test resulted in p > 0.05 what is the next step in determining what is the statistically significant relationship among 3 groups/conditions in One-Way ANOVA? O Check the p-value of ANOVA and if p 0.05, you're done. O Check the p-value of ANOVA and if p > 0.05, run a post-hoc Games-Howell test O Check the p-value of Welch's test and if p
