Assume that the sample is taken from a large population and the correction factor can be ignored. Round the nal answers to four decimal places and intermediate 2 value calculations to two decimal places. Find the probability that the mean of a sample of 25 people is less than 10. P{f10)=D Find the probability that the mean of a sample of 25 people is between 11 and 12. P(11
