At your part-time job in the office, your manager requested that
you examine all accounts receivable of the company, and then to
take a random sample of them to provide her with estimates of the
population values useful for decision making. You considered a
random sample of 45 of the accounts and obtained a mean of $135.40
and a standard deviation of $43.72. Assuming normality for the
distribution of amounts in the accounts receivable, estimate the
upper end point in a 99% confidence interval for the total amount
of the 780 accounts of the company.
