For a random sample of 146 Sacramento households with telephones, what is the probability of the following. (Round μ to the nearest integer, σ to 4 decimal places.)

@Hero It's a statistics question...well from what I can tell. I think that's why there are numbers. I am not good at statistics however but there is a statistics study group.
