Question: Losing weight A Gallup Poll found that 59% of the people in its sample said "Yes" when asked, "Would you like to lose weight?" Gallup announced: "For results based on the total sample of national adults, one can say with 95% confidence that the margin of (sampling) error is ±3 percentage points."14 Does this interval provide convincing evidence that the actual proportion of U.S. adults who would say they want to lose weight differs from 0.55? Justify your answer.
