Questions 17 -19
A company produces rechargeable batteries for small size string trimmers. We define the life of the battery
as the time between starting the string trimmer until the trimmer stops due to battery failure. It is known
that the life of such batteries follows the normal distribution with mean 29.5 minutes and deviation of
1.35minutes.
