Use the data set of 30 numbers above to construct a frequency distribution of 7 classes.
Be sure to include lower and
upper limits, lower and upper boundaries, midpoints,
frequencies, relative frequencies, and cumulative frequencies.
Using the above data set, find the following:
1. Mean 2. Median 3. Mode 4. Standard deviation (assume a sample).
5. Qi 6. Q3
7. Interquartile range.
8. Using the Empirical Rule, between what two values would 68.2% of the data values fall?
9. Using the Empirical Rule, between what two values would 95.4% of the data values fall?
10. Using the Empirical Rule, between what two values would 99.7% of the data values fall?
11. Compute a 75% Chebyshev interval centered about the mean.
12. Compute an 88.9% Chebyshev interval centered about the mean.
12. What would the z-score be for a value of 1420?
13. What would the Z-score be for a value of 1020?
