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

A. Construct an analysis of variance table

Source Variation Sum Squares Degree Freedom Mean Square F P-Value
Treatments
Error
Total

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

Solutions

Expert Solution

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
