The average weekly earnings of bus drivers in a city are $950 (that is m) with a standard deviation of$45 (that is s). Assume that we select a random sample of 81 bus drivers.
b. What is the probability that the sample mean will be greater than $960? c. If the population of bus drivers consisted of 400 drivers, what would be the standard error of the mean? 2.
