QUESTION 1 ANOVA is specically used for the Kudzu problem because There are only two groups to compare " The dependent variable is quantitative " The independent variable is quantitative " The independent variable is categorical and has more than two groups QUESTION 2 For this problem Ho and Ha are Ho: mu(Control)=mu(Low)=mu(High); Ha: At least one of them is different Ho: At least one of them is different; He: mu(Control)=mu(Low)=mu(High) Ho: mu(Control)>mu(Low)>mu(High); Ha: At least one of them is different None of the answers are correct QUESTION 3 The standard assumptions for ANOVA are The data must be completely normal and the smallest standard deviation [the largest standard deviation 2 QUESTION 4 For this problem (Kudzu.csv) The normality and outlier assumptions were passed without question but the standard deviation assumption was almost not passed The normality and outlier assumptions were roughly passed and the standard deviation assumption was easily passed The normality and outlier assumptions were roughly passed but the standard deviation assumption was almost not passed QUESTION 5 The p-value for the analysis ofvariance was 0.003186 I' 0.008668 ' 7.718 ' 0.0014 QUESTION 6 Using an alpha of 0.05 the statistical conclusion is ' ' Reject Ha for Ho ' ' Fail to reject Ha for Ho Fail to reject Ho for Ha ' ' Reject Ho for Ha QUESTION 7 The conclusion in plain English is ' ' There is no statistical evidence that any of the averages for the three groups is different ' The statistical evidence is that at least one of the means is different for any standard alpha (the standard alpha's are 0.10, 0.05, 0.01) \\ The statistical evidence is that at least one of the means is different but only for alphas of 0.10 or 0.05. " The statistical evidence is that all of the means is different but only for alphas of 0.10 or 0.05. ' The statistical evidence is that all of the means are different for any standard alpha. QUESTION 8 The contrast tests showed (use alpha=0.05) The average of high and low dose had a different mean from control; high dose had a different mean vs. low dose O The average of high and low dose had a different mean from control; high dose did not have a different mean vs. low dose The average of high and low dose did not have a different mean from control; high dose had a different mean vs. low dose QUESTION 9 After reviewing the contrast test and then looking at the means for the different groups one would conclude Low dose had a significantly higher average bone density vs. high dose High dose had a significantly higher average bone density vs. control High dose had a significantly higher average bone density vs. low dose
