Problem 1
Expected reasoning: identify the record, preserve provenance, apply the method, test sensitivity, and interpret what the result does not establish.
Key check: A log-log slope is d log y/d log x, not a new measurement.
Instructor solution key
Require traceable input, correct method, explicit assumptions, quantitative evidence, precise citations, and a limitation. Problems are worth 25, 30, 20, and 25 points.
