A random sample of 82 accounts of a company shows the average days sales in receivables is 49 with standard deviation of 20 days. What is the p-value for the test of a hypothesis that the company's average days sales in receivables is 48 days or less?

Use the normal approximation to calculate the p-value (the NORMSDIST() spreadsheet function will come in handy).

Enter answer accurate to three decimal places.
