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.
Use a level 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).

Source of Variation | SS | df | MS | F | P-value | F crit |
Between Groups | 93.33 | 2 | 46.67 | 2.37 | 0.1354 | 3.89 |
Within Groups | 236 | 12 | 19.67 | |||
Total | 329.33 | 14 |
Therefore, F test statistic = 2.37
P value is = 0.1354 > 0.05
Therefore, we fail to reject H0 at
We do not have enough evidence to reject the null hypothesis that the population means are all equal.
