To study the effect of temperature on yield in a chemical process, five batches were produced at each of the three temperature level. The results follow.
50 degree C | 60 degree C | 70 degree C |
32 | 31 | 25 |
22 | 32 | 30 |
34 | 35 | 30 |
37 | 24 | 32 |
30 | 28 | 33 |

B. use .05 level of significance to test whether the temperature level has an effect on the mean yield of processes. Calculate the value of the test statistic
A.
ANOVA ( analysis of variance ) TABLE :
B.
Since it is concluded that the means are not equal,
we conclude that temperature level does have an effect on the mean yield of processes
