About ______% of the area is between z= -1 and z= 1 (or within 1 standard deviation of the mean)? How do you solve this?
1 answer:
Answer:
68%
Step-by-step explanation:
<em><u>68-95-99.7% Rule:</u></em>
<em><u /></em>
This is the empirical rule which is used to remember the percentage of values that is within a band of the mean. We say:
- 68% of the data fall within 1 standard deviation of the mean
- 95% of the data fall within 2 standard deviation of the mean, and
- 99.7% of data falls within 3 standard deviations of the mean
Clearly, from the empirical rule, we see that about 68% of the area is between z = -1 and z = 1 (or within 1 standard deviation of the mean)
