Question

A rural village has 3500 residents. In a random sample of 225 residents, 4 have the flu. Predict roughly the number of residents in the village who have the flu.

Answer 1

Answer: 62

Explanation:

A rural village has 3500 residents and in a random sample of 225 residents, 4 of the residents have the flu. This means 4/225 has the flu

To predict the number of residents in the village who have the flu will be 4/225 multiplied by the total residents. This will be:

= 4/225 ×3500

= 14000/225

= 62.22

About 62 residents have the flu
