The following data are from a completely randomized design. Treatment A B C 1 62 142 12 6 142 1.56 122 165 1.24 138 145 1.42 140 148 1.36 150 1?4 1.52 128 Sample mean 156 142 134 Sample variance 164.4 131.2 110.4 a. Compute the sum of squares between treatments (to the nearest Iwhole 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 ANDVA table for this problem. Round all Sum of Squares to nearest whole numbers. Round all Mean Squares to one decimal place. Round Fto two decimal places. Round your pvalue to four decimal places. 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 f. At the a = 0.05 level of significance, test whether the means for the three treatments are equal. Calculate the value of the test statistic (to 2 decimals). The p-value is - Select your answer - What is your conclusion? - Select your answer -The following data are from a completely randomized design.
