Question
Evaluation: More Than 48 Grams
1. A chemical engineer is trying to increase the amount of the useful product in
a reaction. She performs the reaction with her new equipment 10 times and
gets the following amounts of the useful product:
Amount of
Useful product in
Grams
47.1
48.2
48.3
47.5
48.5
48.1
47.2
48.2
48.4
48.3
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?
