TimeRyte is a company that manufactures highly accurate stopwatches for sporting events. The company has two manufacturing facilities, one on the east cost and one on the west coast. Some stopwatches are assembled with components manufactured at the east coast facility, some are assembled with components manufactured at the west coast facility, and some are assembled with components manufactured at both facilities. TimeRyte have recently started a new advertising campaign that claims their stopwatches are accurate to a thousandth of a second 98% of the time. An independent research company is investigating the reliability of TimeRyte's stopwatches and the honesty of their claim. Their testing revealed that stopwatches assembled with components from the east coast facility are accurate to one thousandth of a second 96% of the time, stop watches assembled with components from the west cost are accurate to one thousandth of a second 99% of the time, and that stopwatches assembled with components from both facilities are accurate to the thousandth of a second 98% of the time.
