Question

47.1 48.2 48.3 47.5 48.5

48.1 47.2 48.2 48.4 48.3
1. What proportion of the reactions were above the 48 grams threshold?
2 .Other chemists typically get 65% of their reactions to produce more than 48 grams. Should the engineer say that she was able to increase the useful product when compared to the other chemists?
Group of answer choices

Answer 1

1. 0.7 since 7 of the 10 reactions had more than 48 grams of the useful product.

2. She could be optimistic, but her proportion does not seem far from what others have done. She should run more reactions to be more sure of the improvement. With only 10 values in her data set, 0.7 (and 0.6) is as close to 0.65 as she could get.
