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.
