Participants from the National Health and Nutrition Examination Survey, 2003-2004, had a mean BMI of 28.3 with a standard deviation of 6.0. Assuming BMI is normally distributed, what is the probability that a randomly selected participant had a BMI measure between 28.3 and 34.3? Use the Empirical Rule.

Expert Solution
Step 1: Introduce the given information

Given,

Mean, μ = 28.3

Standard deviation, σ = 6.0

Using formula (Empirical rule),

According to empirical rule 68% of data lies within one standard deviation of the mean. That is, 68% of data lies between mu minus sigma and mu plus sigma.
