Answer:
According to the Empirical Rule, 68% of the data should fall between 11.98 and 18.02
Step-by-step explanation:
We are given the following data in the question:
10, 11, 12, 13, 13, 13, 14, 15, 16, 16, 17, 18, 18, 19, 20
Formula:
where
are data points,
is the mean and n is the number of observations.
Sum of squares of differences = 25 + 16 + 9 + 4 + 4+ 4 + 1 + 0+ 1+ 1 + 4 + 9 + 9+ 16 + 25 = 128
![S.D = \sqrt{\dfrac{128}{14}} = 3.02](https://tex.z-dn.net/?f=S.D%20%3D%20%5Csqrt%7B%5Cdfrac%7B128%7D%7B14%7D%7D%20%3D%203.02)
Empirical rule:
- According to this rule almost all the data lies within three standard deviation of the mean for a normal distribution.
- About 68% of data lies within one standard deviation of the mean.
- About 95% of data lies within two standard deviations of mean.
- Arround 99.7% of data lies within three standard deviation of mean.
Thus, by empirical rule,
![\mu \pm 1\sigma = 15\pm (3.02) = (11.98,18.02)](https://tex.z-dn.net/?f=%5Cmu%20%5Cpm%201%5Csigma%20%3D%2015%5Cpm%20%283.02%29%20%3D%20%2811.98%2C18.02%29)
According to the Empirical Rule, 68% of the data should fall between 11.98 and 18.02
