Read and compare dot plots, histograms, and box plots to describe center, spread, and shape.
Use display shape to judge a claim
Problem
A delivery-time histogram has its highest bars at \(20\text{--}30~\text{minutes}\) and a long tail toward higher times. Evaluate Claim A, “There is very little variation,” and Claim B, “Most deliveries are fairly quick, but some take much longer.” Which complete response is supported by the display?
Judge each claim against both the main cluster and the tail. The tallest bars show what is typical for most deliveries, while the distance and direction of the thinning bars show whether some times extend far from that cluster. A strong claim must account for both features, not just the peak.
