adult men in the United States are randomly selected and measured for their body mass index (BMI). Based on that sample, it is estimated that the average (mean) BMI for men is 25.5 , with a margin of error of 3.2 . Use the given statistic and margin of error to identify the range of values (confidence interval) likely to contain the true value of the population parameter.
