Here the age of an unpaid account is the number of days elapsed since the invoice date. To test this theory, the accountant randomly selects independent samples of 500 accounts with ages between 31 & 60 days and 500 accounts with ages between 61 & 90 days from the accounts receivable ledger dated one year ago. When the sampled accounts are examined, it is found that 10 of the 500 accounts with ages between 31 & 60 days were eventually classified as "uncollectible", while 27 of the 500 accounts with ages between 61 & 90 days were eventually classified as "uncollectible". Let pi = proportion of accounts with ages between 31 & 60 days and pa - proportion of accounts with ages between 61 & 90 days. 10 points (5) Give the null and alternative hypotheses to test the station manager's theory.
