Hello!

I'm having trouble with this practice problem. I tried doing an Anova test (single and two factor) in Excel, but I obviously didn't get the right answer.

Part A

To test for am:r signicant difference in the number of hours between breakdowns for four machines, the following data were obtained. 1 2 .3. 4 5.3 0.9 11.0 10.0 8.2 7.5 10.2 12.1r 5.? 9.5 2.6 10.4 0.? 9.5 2.4 10.0 {a} At the a: = 0.05 level of significance, what is the difference, if any, in the population mean times among the four machines? State the null and alternative hypotheses. O Hn:p1p2#p3p4 Hau:l'*':1=1\"2=i"3=f'4 O Ho:-\"1=F'2=-\"3=\"4 Ha:p1p2p3p4 O Ho: At least two ofthe population means are equal. Ha: At least two of the population means are different. O Ho: Not all the population means are equal. Ha:\"1=1\"2=\"3=f'4 O \"0:\"1=J\"2=\"3=\"4 Ha: Not all the population means are equal. Find the value of the test statistic. (Round your answer to two decimal places.) E Find the p-value. (Round your answer to three decimal places.) p-value = State 1,rour conclusion. O Reject Hg. There is sufficient evidence to conclude that the mean time between breakdowns is not the same for the four machines. 0 Reject H0. There is not sufcient evidence to conclude that the mean time between breakdowns is not the same for the four machines. 0 Do not reject H0. There is sufcient evidence to conclude that the mean time between breakdowns is not the same for the four machines. 0 Do not reject H0. There is not sufcient evidence to conclude that the mean time between breakdowns is not the same for the four machines.
