5. Using the given sample values, answer the following without utilizing classes.

Values: 68, 70, 62, 89, 73, 65, 92, 86, 73, 62, 83, 87, 94, 87, 73, 67, 97, 75

5.1 Determine the five measures of centrality and the four measures of variation

5.2 Determine the upper and lower bounds that delimit the lower 20% and the upper 80% of the sample distributions values

5.3 Assuming the sample is representative of the population and assuming the populations shape (geometry) is unknown, determine the upper and lower bounds that that are symmetric about the mean and that contain 80% of the populations data

5.4 By hand, construct the Box and Whisker and Stem and Leaf representations.
