Question

A manufacturer sent free boxes of tissue to 100 random homes in Miami at the beginning of January. At the end of January, a representative found an average of 3 boxes of tissues had been used in each home. The representative concluded that the average home in the United States uses 36 boxes of tissue per year. Is his conclusion correct

Answer 1

conclusion of representative is incorrect

Explanation:

The total random samples of 200 homes in Miami uses 3 boxes of tissues per home.

This is true only for Miami. Miami's population is not the correct representation of the population of USA.

Also, there are several other factors such as population group residing in Miami, their education level, heath etc. plays a major role as a variable. These variables in case of USA will be entirely different.

Hence, conclusion of representative is incorrect
