Find the mean, the median, and the mode in each of the following list of data. a. 8, 3, 3, 17, 9, 22, 19 b. 11, 8, 2, 5, 17, 39, 52, 42 c. 101, 88, 74, 60, 12, 94, 74, 85 2. A professor grades students on 5 tests, a project, and a final examination. Each test counts as 10% of the course grade. The project counts as 20% of the course grade. The final examination counts as 30% of the course grade. Samantha has test scores of 70 65, 82, 94, and 85. Samantha's project score is 92. Her final examination score is 80. Use the weighted mean formula to find Samantha's average for the course. Hint: The sum of all the weights is 100%. 3. A salesperson records the following daily expenditures during a 10-day trip.
