Each member of a random sample of 20 business economists was asked to predict the rate of inflation for the coming year. Assume that the predictions for the whole population of business economists follow a normal distribution with standard deviation 2%. Find any pair of values such that the probability that the sample standard deviation lies between these values is 0.90.
