Refer to the Lincolnville School District bus data. Information provided by manufac-turers of school buses suggests the mean maintenance cost per year is $4,400 per bus with a standard deviation of $1,000. Compute the mean maintenance cost for the Lin-colnville buses. Does the Lincolnville data seem to be in line with that reported by the manufacturer? Specifically, what is the probability of Lincolnville's mean annual mainte-nance cost, or greater, given the manufacturer's data?
