Question
Chapter 3.2, Problem 3.22E
To determine
To calculate the proportion of the data that falls above than 100.
Expert Solution & Answer
Answer to Problem 3.22E
84% of the values fall above than 100.
Explanation of Solution
Given:
Standard deviation = 11
Concept used:
As per
- 68% of the data falls within one standard deviation from the mean.
- 95% of the data falls within two standard deviations from the mean.
- 99.7% of the data falls within three standard deviations from the mean.
Calculation:
100 is one standard deviation less than mean, the proportion that falls above than 100 is 34% + 50% = 84%.
Therefore, approximate 84% of the values fall above than 100.
