To study the effect of temperature on yield in a chemical process, five batches were produced at each of three temperature levels. The results follow:

Temperature

50C- 30, 20, 32, 35, 28 60C- 29, 30, 33, 22, 26 70C- 21, 26, 26, 28, 29

a.Construct an analysis of variance table (to 2 decimals butp-value to 4 decimals, if necessary).

b.Use alevel of significance to test whether the temperature level has an effect on the mean yield of the process.

Calculate the value of the test statistic (to 2 decimals).
