Chapter 14.5, Problem 31E

A survey was conducted to investigate interest of middle-aged adults in physical-fitness programs in Rhode Island, Colorado, California, and Florida. The objective of the investigation was to determine whether adult participation in physical-fitness programs varies from one region of the United States to another. Random samples of people were interviewed in each state, and the data reproduced in the accompanying table were recorded. Do the data indicate differences among the rates of adult participation in physical-fitness programs from one state to another? What would you conclude with α = .01?
