A health magazine reported that 27 of adult males smoke cigarettes To test this claim they select 40 adult males at random and record if they smoke cigarettes They calculate a 95 confidence interval for the proportion of adult males who smoke and find it is 22 to 28 Interpret the confidence interval O We are 95 confident that the interval from 0 22 to 0 28 captures the true proportion of adult males who smoke O If the magazine took many random samples of 40 adult males then 95 of the constructed confidence intervals would capture the true proportion of adult males who smoke The interval from 0 22 to 0 28 captures 95 of the adult males who smoke
