a super, new fertilizer that was suppose to make plants
produce twice as many tomatoes as untreated plants. Mrs.
LePorte wanted to test the fertilizer producer’s claim. She set
up two groups of 10 plants each. Group A was left untreated,
and group B was treated with the fertilizer. Group A produced
346 tomatoes, while group B produced 432 tomatoes.
What should the conclusion be?
While the treated tomato plants produced more
tomatoes, it did not produce twice as many
tomatoes. Thus, the fertilizer producer’s claim
is false.
