Problem 8

For Problems 1–8, find the critical value(s) for :

8. right-tailed test with  = 0.01, degrees of freedom in the numerator = 55, degrees of freedom in the denominator = 50.

Step-by-Step Solution:

Step 1 of 5) Degrees of freedom in the numerator = 55, degrees of freedom in the denominator = 50. Verifying the Normality Requirement in a Two-Way ANOVA Again, to conduct any ANOVA, the response variable must be normally distributed. This requirement can be verified by drawing a normal probability plot of the residuals in the ANOVA model. Verifying the Normality Requirement in a Two-Way Analysis of Variance Problem Verify the normality requirement for the HDL data analyzed in Example 3. Approach We will use Minitab to obtain the residuals and draw the normal probability plot. Solution Figure 19 shows the normal probability plot of the residuals. Because the residuals all lie within the confidence bands, the normality requirement is satisfied. If we use StatCrunch to assess normality of the residuals, we find the correlation between the residuals and expected z-scores is 0.981. Because 0.981 7 0946 (critical value from Table VI with n = 18), it is reasonable to conclude the residuals are normally distributed.
