Brink’s Inc.Aaron FinkJennifer Jones

Case SummaryIn May, 1978, Brink's Inc. was awarded a contract to collect coins from some 70,000 parking meters in New York City for delivery to the City Department of Finance. In April of 1980, five Brink's collectors were arrested and charged with grand larceny. The court was satisfied that theft has taken place, but the actual amount of shortage was in question.

HypothesisBrink should be convicted of larceny because there is enough evidence from May 1978 to April 1980.

Using a 90% Confidence Interval, is there enough evidence to conclude that there are shortages in monthly collections while Brinks was under contract? Is there enough evidence to conclude that monthly collections return to normal levels after Brinks ends their contract?
