Question
Forty 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 26.5, 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. The range of values likely to contain the population parameter is from to. (Type an integer or a decimal. Use ascending order.)Explanation / Answer
mean = 26.5
margin of error = 3.2
interval = mean +/- margin of error
= (26.5 - 3.2 , 26.5 + 3.2)
= (23.3 , 29.7)
