41 credit card holders are selected at random. For each, their current credit card balance is recorded. The average for these 41 people is = $600. Assume that the current balance of all credit card holders follows a normal distribution with unknown mean μ, and that a 85.3% confidence interval for μ is found to be $600 ± 32.9. Find the standard deviation σ of the population?
