Answer:
It would be correct to conclude that approximately 68 percent of the scores would fall between 85 and 115.
Step-by-step explanation:
We are given the following in the question:
Mean, μ = 100
Standard Deviation, σ = 15
We are given that the distribution is a bell shaped distribution that is a normal distribution.
Empirical rule
- Also known as 68-95-99.7 rule.
- It states that almost all data lies within three standard deviation of mean for a normal distribution.
- About 68% of data lies within one standard deviation of mean.
- About 95% of data lies within two standard deviation of mean.
- About 99.7% of data lies within three standard deviation of mean.
Thus, approximately 68% of data will lie within one standard deviation of mean.
Thus, it would be correct to conclude that approximately 68 percent of the scores would fall between 85 and 115.
14 times 17 is 238.
I will draw an area model and add it to my answer.
Hope this helps!!!
