Question
A group of people estimate the number of Blue m&m's in a large jar. They each take a sample of 20 m&m's and count the number of blue m&m's before returning them to the jar. Here is the data from the samples:Number of Blue m&m's Number of Samples4 25 56 97 78 39 110 211 1What percent of samples had 4 or fewer blue m&m's? Round to the nearest tenth of a percent.
Solution
To answer this question, we first need to determine the total number of samples and the number of samples that had 4 or fewer blue m&m's.
From the data, we can see that the number of samples that had 4 or fewer blue m&m's is 25 (the number of samples that had 4 blue m&m's).
The total number of samples is the sum of the number of samples for each number of blue m&m's. This is 25 (for 4 blue m&m's) + 5 (for 5 blue m&m's) + 9 (for 6 blue m&m's) + 7 (for 7 blue m&m's) + 3 (for 8 blue m&m's) + 1 (for 9 blue m&m's) + 2 (for 10 blue m&m's) + 1 (for 11 blue m&m's) = 53 samples.
The percent of samples that had 4 or fewer blue m&m's is then (25 / 53) * 100 = 47.17%.
Rounding to the nearest tenth of a percent, we get 47.2%. So, 47.2% of samples had 4 or fewer blue m&m's.
