The police chief of a town is trying to determine the average speed of drivers on a specific road.
• The chief took a random sample of the speeds of 100 drivers on the road.
• The mean was 48.5 mph, with a standard deviation of 2.5 mph.
Which choice would decrease the margin of error?
(Note: margin of error ≈ 2 ns where s is the sample standard deviation and n is the sample size.)
decreasing the sample size
increasing the sample size
changing the time that the data is collected
changing the road on which the data is collected
