Question

Vector performed an experiment at a local farm to determine if the addition of bananas to his biomass cow manure recipe helps produce more or less energy. He collected random samples of manure and bananes from the farm, prepared 15 bottles each of both mixtures, and placed a balloon on top of each bottle. After two weeks, he measured the circumference of each balloon in centimeters, the bigger the balloon grow, the more energy that was produced. The results of the experiment are displayed in the box plots below. What can Vector report to his local Biogas Club about the results of his experiment?

Answer 1

Notice that the maximum of the cow manure is 26 , while the minimum of mashed bananas is 22. There are also some values for the mashed bananas, that compare or are even lower than the maximum of cow manure biogas production. Then, for example mixing cow manure and bananas, may produce a number that is lower than the maximum for only cow manure.

Therefore, this time we select the very first answer (top left) that states that:

"About 75% of the time, the mixture of cow manure and mashed bananas is likely to produce more biogas than only cow manure in THIS farm"

Notice as well, that one cannot extend any result to the entire country, given that in this particular location, the environmental conditions resulted in the given biogas production, and other latitudes may not be well represented by this data. So have in mind that any other statement that talks about what would happen in the "COUNTRY", instead of in this farm, cannot be accepted as correct. This way one can exclude the two statements on the right.

Please select the top left statement as your answer.
