Below are sample questions representative of the exercises included on this worksheet and related ALG2.227 Using Statistical Models for Decision Making skill assessments:

Problem 1Difficulty: Mastery

A regression model was built before a new policy changed how customers are billed. Which statement is the best limitation to report?

AR-squared prevents any change over time

BPast regression always stays accurate after major changes

CA policy change makes extrapolation certain

DThe relationship may have changed, so the model should be updated and predictions have increased uncertainty

Solution & Explanation:A model is only as good as the conditions under which data were collected. A major change can shift the relationship, so the model should be re-fit or re-validated and uncertainty should be emphasized.

Problem 2Difficulty: Mastery

A warehouse can rent an extra truck. If it does NOT rent, shipping costs $4.50 per package. If it DOES rent, it pays a fixed $150 plus $3.20 per package. Tomorrow's packages shipped: - 65% chance: 400 packages - 35% chance: 650 packages Compute (expected cost with truck) - (expected cost without truck). (Round to the nearest cent.)

Solution & Explanation:E[packages] = 0.65(400)+0.35(650)=487.5. Expected cost without = 4.50(487.5)=2193.75. Expected cost with = 150 + 3.20(487.5)=150+1560=1710. Difference = 1710-2193.75 = -483.75 (renting saves money on average).

Problem 3Difficulty: Mastery

A contract is approved only if the production model predicts at least 450 units. Regression predicts units y from training hours x: y = 300 + 15x Typical prediction error is about 30 units. To be conservative, require (predicted - 30) >= 450. What is the minimum x that meets this rule?

Solution & Explanation:Use conservative inequality: (300 + 15x) - 30 >= 450 -> 270 + 15x >= 450 -> 15x >= 180 -> x >= 12.
