The effective life (in hours) of batteries is compared by material type (1, 2 or 3) and operating temperature: Low (10C), Medium (20C) or High (45C). Twelve batteries are randomly selected from each material type and then randomly allocated to each temperature level. The resulting life of all 36 batteries is shown in the following table. Assume a 5% significance level for all questions.
