Please help confirm I am correct: The mean number of push-ups performed in a cross-fit class in the population is u with a standard deviation of 6. Researchers are interested in whether a sample of 36 individuals in a new cross-fit class perform less push-ups than the population average. What is the probability that the mean number of push-ups performed by the sample of individuals in this new cross-fit class is 1 unit below the the population mean (or less)? I'm getting different answers- it is it 1, -1, .16 or .24? help! Thanks
