Answer :
The 68-95-99.7 rule, also known as the empirical rule, is a guideline for understanding the distribution of data in a normal distribution. This rule states the following:
1. 68% of data falls within 1 standard deviation from the mean.
2. 95% of data falls within 2 standard deviations from the mean.
3. 99.7% of data falls within 3 standard deviations from the mean.
For this question, you're asked about the 95% part of this rule. This means we need to find out how many points on either side of the mean contain 95% of all values.
According to the rule:
- 95% of values fall within 2 standard deviations from the mean.
Therefore, the answer is that 95% of all values fall within 2 standard deviations on either side of the mean.
1. 68% of data falls within 1 standard deviation from the mean.
2. 95% of data falls within 2 standard deviations from the mean.
3. 99.7% of data falls within 3 standard deviations from the mean.
