A car factory produces a variable number of cars to keep up

A car factory produces a variable number of cars to keep up with the demand. The following measurements, made at the start of each month, show the rate at which cars are produced (in hundred cars/month): Make an overestimate and an underestimate of the total number of cars produced in the first month. overestimate - 7 tons underestimate = 5 tons Make an overestimate and an underestimate of the total number of cars produced for the whole six months for which we have data.

Solution

A) overestimate = 7

underestimate = 5

B) overestimate = (7 + 12 + 15 + 15 + 13 + 12)/6 = 74/6 = 12.333

underestimate = (5 + 7 + 12 + 13 + 12 + 10)/6 = 59/6 = 9.83333
