Suppose babies boom in a large hospital have a mean weight of 3181 grams, and a standard deviation of 526. If 97 babies are sampled at random from the hospital, what is the probability that the mean weight of the sample babies would differ from the population mean by less than 53 grams? (Round your answer to 4 decimal places) The quality control manager at a computer manufacturing company believes that the mean life of a computer is 120 months, with a variance of 100.
