Readers of a national magazine were asked to rate their satisfaction with 36 restaurant chains in the United States on a scale from 0 to 100. Each chain was then classified as a low-price restaurant (under $16 per person) or a high-price restaurant ($16 or more). Assume that all conditions for the Mann-Whitney test have been met.
