Question

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 in grams:
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?

Answer 1

Answer:

1. 70%

2. Yes

Step-by-step explanation:

1. there are 7 that are over 48, and 10 total. so, 7/10, or 70% would be our answer.

2. 70% is greater than 65%, so yes. he did it better than them.
