H0: (The treatment means are not all the same or The treatment means are the same?)
H1: (The treatment means are not all the same or The treatment means are the same?)
b. What is the decision rule? (Round the final answer to 2 decimal places.)
Reject H0 if the test statistic is greater than __________
c. Compute SST, SSE, and SS total. (Round the final answers to 3 decimal places.)
SS total =
d. Complete the ANOVA table. (Round the SS, MS, and F values to 3 decimal places.)
e. State your decision regarding the null hypothesis.
(Do not reject or Reject?) H0.
Using Excel<data<data analysis< one-way ANOVA test
H0: Null hypothesis: The treatment means are the same
