According to an automobile association, the average cost of a
gallon of regular unleaded fuel at gas stations in a certain month
was $2.834. Assume that the standard deviation of such costs is
$0.15. Suppose that a random sample of nequals100 gas stations is
selected from the population and the month's cost per gallon of
regular unleaded fuel is determined for each. What is the
approximate probability that the sample has a mean fuel cost
between $2.84 and $2.86? (four...
