Chapter 6: Q.40 (page 386)

About what percent of x values lie between the first and third standard deviations(both sides)?

Short Answer

Expert verified

About 32% of the x values from normal distribution will lie between first and third 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 third standard deviations(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 three standard deviations of the mean, there are approximately 99.7%values of xlies. So, the percent of the xvalues from normal distribution lie between first and third standard deviation from the mean will be:

=99.7%鈭�68%

=31.7%

鈮�32%
