7. Suppose it is claimed that amongst the population of human adults, the number of hours spent sleeping per day is normally distributed with a mean of μ = 7 and variance of o² = 1.1 Further suppose that we wish to study the mean of the population by taking a random sample of n = 62 adults. U 8. Following on from the previous question, what is the probability that when we take a random sample of n = 62 adults, the sample mean would be greater than 7.133?
