The range of data values that will allow 71% of the data to fall within the mean of symmetry is -
0.2552 and 4.2552.
11. What is the variance of this data set?
o² = (2.1275)²
o2 = 4.5263
Given that the standard deviation is 2.1275 and it is the square root of the variance,
5.576

the value of the variance is 4.5263.
12. Are there any outliers with this data set? (Outliers refer to data points that lie beyond 3
standard deviation from the mean).

Determine the percentage in between these scores. Draw the curve and show your complete
solution.
