Explanation / Answer

(According to Chegg policy, only four subquestions will be answered. Please post the remaining in another question)

(The table for the first two questions is missing. Starting with question 3.)

3. Mode is 119.

Variation ratio = 1 - 119/329

= .6383.

4. 11, 12, 12, 14, 11, 10, 18

Sorting: 10, 11, 11, 12, 12, 14, 18

Median is the midle value i.e 12.

5. 56, 54, 45, 48, 56, 56, 50, 51, 52, 59

Sorting: 45, 48, 50, 51, 52, 54, 56, 56, 56, 59

Median is the average of the middle values i.e (52 + 54)/2 = 53.

6. 2, 3.5, 4, 2, 3, 2, 1

Mean is (2 + 3.5 + 4 + 2 + 3 + 2 + 1) / 7

= 17.5/6 = 2.5

Variance = (0.52 + 12 + 1.52 + 0.52 + 0.52 + 0.52 + 1.52) / 6

= 1.08.
