Answer: 95%
Step-by-step explanation:
The Empirical rule says that about 68% of the data is within one standard deviation of the mean; about 95% of the data is within two standard deviations of the mean ; about 99.7% of the data is within three standard deviations of the mean.
Given : Sample mean :
Standard deviation:
To find the percentage of house sizes that lie between 955.7 and 1454.1 sq ft.
We can write it as
and
Thus, 955.7 is 2 standard deviations left from the means and 1454.1 is 2 deviations right from the mean.
Then by empirical rule , about 95% of house sizes that lie between 955.7 and 1454.1 sq ft .
