We'll represent Louise's, Tammy's, Delores's, and Sheryl's point values with ,
,
, and
respectively since each one is 1 point more than the last.
Add all of these values up and set it all equal to .
Now, simplify.
Subtract on both sides.
Divide both sides by .
Since Louise's score is , the answer is
.
To verify our answer, add the point totals ,
,
, and
.
This equals , so we can be sure the answer is correct.
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
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,
According to the Empirical Rule, 68% of the data should fall between 11.98 and 18.02
