May decides to purchase the store and records the accounts for a period of three months from the date of purchase. She then takes a random sample of 20 business days from those three months and finds that the store did gross over $850 per day for fewer than 6 business days in her sample. Do you think this should this make May suspect that p (the probability of grossing over $850 on a business day) is now less than 0.7? Explain your answer
