Given the following sample data, complete parts a and b. Click the icon to view the sample data. a. Based on the computations for the within- and between-sample variation, develop the ANOVA table and test the appropriate null hypothesis using a = 0.01. Use the p-value approach. b. If warranted, use the Tukey-Kramer procedure to determine which populations have different means. Use a = 0.01. Click the icon to view a table of critical values for the F distribution for α = 0.05. Click the icon to view a table of critical values for the F distribution for a = 0.01. Click the icon to view a table of q-values for 1-a = 0.95.
