Question

In order to compare the life expectancies of three different brands of printers, eight

printers of each brand were randomly selected. Part of the resulting Analysis of Variance table is presented below:

Source of Variation	Sum of squares	Degrees of freedom	Mean square	F-statistic	p-value
Printer Brand	?	2	?	?	0.0081
Error	770	?	?
Total	1218	23

We are interested in comparing the mean life expectancies for the three brands of printer using a significance level ^α ⁼ 0.05 .

c. Given the p-value provided in the Analysis of Variance table, decide whether to reject H₀in favour of H_aor to fail to reject H₀.

d. Based on your decision in part (c), write your conclusion for the test in the context of the situation. Be specific.
