Week 2 Assignment
Assignment 2 Instructor Comments:
1. Just multiply each value by its weight; add them together; then divide by the sum of all the weights.
2. Most everybody gets these right—just use the formulas in the book as a guide. Give the answers in 2 place decimals—not as a fraction.
3. As with item 2, most students get the first 5 correct and the last 2 wrong. Hint—the last two problems are mathematically the same as the 5th one. Why? Give the answers in 3 place decimals.
Question 1
- Compute the weighted mean for the following data.
Question 2
- If P(A) = 0.50, P(B) = 0.40, and P(A ∪ B) = 0.88, then P(B | A) =
