Assume the credit card balances of younger college educated employed persons are normally distributed with a mean of $ 6,358 and a standard deviation of $1,907 – assume these are population values. What is the probability of a randomly selected credit card holder has a credit card balance less than $5500?   Use the standard normal table for this or the Normal 2020.xlsx file, using the population mean and standard deviation.    Use 4 significant decimal places for your answer, and use the proper rules of rounding.  I am looking for just the answer, not the equation.
