a. Construct an analysis of variance table (to 2 decimals, if necessary).
Source of Variation Sum of Squares Degrees of Freedom Mean Square
F
Treatments
Error
Total
b. Use a .05 level of significance to test whether the temperature level has an effect on the mean yield of the process.
The p-value is greater than .10
What is your conclusion?
Conclude that the mean yields for the three temperatures are all equal
