Answer:

The complete question is:

A town of 48,730 residents is implementing a new cancer screening for all residents. One half of one percent (0.5%) of people in the town actually have the disease. The test has a 92% accuracy rate for positive results, with an 8% false positive rate for detecting cancer.

How many people in the town have cancer? How many do not? Explain your answers.

Explanation:

We have to find out the percentage of people who actually have caner. It is given that the percentage is 0.5%.

As 0.5% = 0.005

People having caner: 244

People not having cancer: 48,486
