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.
