Cell Phone Lifetimes A recent study of the lifetimes of cell phones found the average is 24 months. The standard deviation is 4.2 months. If a company provides its 33 employees with a cell phone, find the probability that the mean lifetime of these phones will be less than 23.8 months. Assume cell phone life is a normally distributed variable, the sample is taken from a large population, and the correction factor can be ignored. Use a TI-83 Plus/TI-84 Plus calculator. Round your answer to at least four decimal places. P(X< 23.8)=
