Hi! Since there are five batches in the ANOVA test below, I'm assuming the null hypothesis would be that all five batches are equal. Is it not true? Also, how do I find the test statistic for an ANOVA test? Thank you!

Use the following for questions 11 and 12. To study the effect of temperature on yield in a chemical process, five batches were produced at each of three temperature levels, and the yield for each batch was recorded. Below is a partial ANOVA table for the data. We are interested in determining if the average yield changes with temperature using of = 0.05. Source SS DF MS F p-value Treatment 70.0 2 Error 236.0 12 Total 306.0 14 What is the null hypothesis? O #1 = /2 = M3 = /4 O M1 = M2 = #3 O Not all of the population means are equal. O #1 = /2 = #3 = /4 = #5
