Chapter 6: Q.39 (page 386)

About what percent of xvalues lie between the first and second standard deviations from the mean (both sides)?

Short Answer

Expert verified

About 27% of the x values from normal distribution will lie between first and second standard deviation.

Step by step solution

01

Given information

Given in the question that, We have to find the percent of xvalues lie between the first and second standard deviations from the mean (both sides)

02

Explanation

According to the empirical rule of normal distribution, within one standard deviation of the mean, there are approximately 68%values of xlies and within two standard deviations of the mean, there are approximately95%values of xlies. So, the percent of the xvalues from normal distribution lie between first and second standard deviation from the mean will be:

=95%鈭�68%

=27%

Therefore, about 27% of the x values from normal distribution will lie between first and second standard deviation.
