According to the records of a soft drink company, the bottles for their one-liter-sized products contain an average (mean) of 1.015 liters of beverage, with a standard deviation of 0.13 liters. As part of routine quality assurance, a sample of 70 bottles has been taken. The sample mean amount of beverage in these 70 bottles was 0.987 liters. Assuming the company's records are correct, find the probability of observing a sample mean of 0.987 liters or less in a sample of 70 bottles. Carry your intermediate computations to at least four decimal places. Round your answer to at least three decimal places. X
