Extracted text: A study being done on college students found that the mean amount of sleep that a college student receives per night is 6.7 hours with a standard deviation of 1.5 hours. Suppose a random sample of 40 college students is taken. Find the probability that the mean amount of sleep will be less than 7.1 hours. Round your standard deviation to two decimal places.
