1. What you will learn

Solve two linked decisions as a pair: retrieval: attempt the two part analysis sample without worked examples. Use the target of each question to decide which information matters, and record your initial response before reading its explanation.

2. Practice

Policy review for parts inspected, case 2: a proposal is eligible only if it reduces delay and stays within budget. Proposal P reduces delay, but no budget information has been supplied.

Rules out eligibility

P stays within budget.
P exceeds the budget.
P has a memorable name.
Another proposal was rejected.
Some proposals reduce delay.

An unmeasured staffing increase occurred only in the reminder group.
The reminder screen used a new color.
The analyst likes reminders.
Other towns use different software.

Weakens

Randomly assigned controls without reminders had no comparable decline.
