question 5

Multiple Choice

Three brands of AAA batteries are compared to determine if differences in
Lifetime exist. Each brand is tested in four devices (TV remote, hand-held game,
Flashlight and digital camera) . The experiment is run once for each combination of brand
And device. The twelve runs are ordered randomly. The time (in minutes) that each
Battery lasts under continuous usage is recorded. Suppose the P-value associated with the
F-statistic for testing whether brand affects battery lifetime is 0.128. Based on this we
Can conclude that

• A) we should reject the null hypothesis.
• B) there is a difference in the mean lifetimes among the different brands.
• C) there is a difference in the mean lifetimes among the different devices.
• D) there is no significant interaction effect.
• E) there is no difference in the mean lifetimes among the different brands.
