A fast food chain operation is interested in determining whether the mean per customer purchase differs by day of the week.To test this,it has e selected random samples of customers for each day of the week.The analysts then ran a one-way analysis of variance generating the following output: Anova: Single Factor
SUMMARY ANOVA Based upon this output,which of the following statements is true if the test is conducted at the 0.05 level of significance?
A)The null hypothesis that population means are equal should be rejected.
B)Based upon Hartley's F-test,we can reject the hypothesis that the population variances are equal.
C)There is justification for applying the Tukey-Kramer method for multiple comparisons.
D)The experiment is a balanced design.
