Time left 0:26:3
The company claims that its batteries are good, on average, for at
most 38 months. A consumer protection agency tested 23 such
batteries to check this claim. It found the mean life of these 23
batteries to be 35 months with a standard deviation of 2
months. Can you conclude that the claim of this company is true?
0.05. Assume that the life of such a battery has an
Use a =
approximately normal distribution.
According to this information the null and alternative hypotheses
are:
Select one:
a. HO: u s 65
H1:μ = 65.
O b. HO: µ 2 65
H1: p < 65
C. HO: u s 65
H1: u > 65
d. HO: u 2 65
H1: u = 65
