a. Compute the sum of squares between treatments (to the nearest whole number).

b. Compute the mean square between treatments (to 1 decimal).

c. Compute the sum of squares due to error (to the nearest whole number).

d. Compute the mean square due to error (to 1 decimal).

e. Set up the ANOVA table for this problem. Round all Sum of Squares to nearest whole numbers. Round all Mean Squares to one decimal place. Round F to two decimal places. Round your p-value to four decimal places. Source of Variation Sum of Squares Degrees of Freedom Mean Square F p-value Treatments Error Total
