Question

for a normal distribution with a mean of 60 and a standard deviation of 5, what x values separate the middle 95% from the extreme values? a. x

Answer 1

For a normal distribution with a mean of 60 and a standard deviation of 5, the x values that separate the middle 95% from the extreme values can be determined within 2 standard deviations from the mean.

Explanation:

In a normal distribution, approximately 95% of the data falls within 2 standard deviations of the mean.

Lower value: 60 - (2 * 5) = 50

Upper value: 60 + (2 * 5) = 70

Answer: Therefore, the x values that separate the middle 95% from the extreme values, within 2 standard deviations, are approximately 50 and 70.
