Question
The ANOVA summary table for an experiment with five groups with seven values in each group is shown to the right Complete parts (a) through (d) below At the 0 05 level of significance state the decision rule for testing the null hypothesis that all five groups have equal population means Determine the hypotheses Choose the correct answer below equal equal Find the test statistic (Round to two decimal places as needed ) Determine the critical value (Round to two decimal places as needed ) What is your statistical decision? Not all the means are There is evidence to conclude that there is a difference in the population means of the groups At the 0 05 level of significance what is the upper-tail critical value from the Studentized range distribution? (Round to two decimal places as needed ) To perform the Tukey-Kramer procedure what is the critical range' Critical range = (Round to three decimal places as needed )Explanation / Answer
a) Ho : miu1 = miu2 = .... = miu
b) H1 : not all means are equal
Fstats = 3.00
F critical value = 2.69
since Fstats is greater than critical value we reject Ho
