At a .05 level of significance, is there a significant difference between the treatments?
What does the P-value = ?
2) 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.
a) Construct an analysis of variance table (to 2 decimals, if necessary) Fill in for ?s
Use a .05 level of significance to test whether the temperature level has an effect on the mean yield of the process.
b) Calculate the value of the test statistic (to 2 decimals)
c) P-value= ?
