• C.

Mode is 75, Mean is 115 and the outlier is 15

• D.

Mode is 15, Mean is 23 and the outlier is 75

D. Mode is 15, Mean is 23 and the outlier is 75
Explanation
The mode is the value that appears most frequently in a set of data. In this case, the number 15 appears twice, which is more than any other number, making it the mode. The mean is the average of all the numbers in the set. To find the mean, we add up all the numbers and divide by the total count. In this case, the sum of all the numbers is 115 and there are 5 numbers, so the mean is 115/5 = 23. An outlier is a value that is significantly different from the other values in the set. In this case, the number 75 is much larger than the other numbers, making it the outlier.

Yes his average is a 3.25

• C.

No his average is a 2.85

• D.

No his average is a 2.75

D. No his average is a 2.75
Explanation
To find Manny's average, we add up all his Habits of Work scores and divide by the number of scores. In this case, the sum of the scores is 2.0 + 1.5 + 4.0 + 1.0 + 4.0 + 4.0 = 16.5. Since there are 6 scores, the average is 16.5 / 6 = 2.75. Therefore, the correct answer is "No his average is a 2.75."

• B.

• C.

Median 7, Range 11

• D.

Median 4, Range 13

C. Median 7, Range 11
Explanation
The median of a set of data is the middle value when the data is arranged in ascending or descending order. In this case, when the data is arranged in ascending order, it becomes 2, 4, 4, 6, 7, 9, 13. The middle value is 6, so the median is 6.

The range of a set of data is the difference between the maximum and minimum values. In this case, the maximum value is 13 and the minimum value is 2. The difference between them is 11, so the range is 11.
