Question

The data represents the body mass index (BMI) values for 20 females. Construct a frequency distribution beginning with a lower class limit of 15.0 and use a class width of 6.0. Does the frequency distribution appear to be roughly a normal distribution? Does the frequency distribution appear to be roughly a normal distribution? A. No, although the frequencies start low, increase to some maximum, then decrease, the distribution is not symmetric. B. No, although the distribution is approximately symmetric, the frequencies do not start low, then increase to some maximum frequency, then decrease. C. Yes, all of the requirements are met. D. No, the distribution is not symmetric and the frequencies do not start off low.

Explanation / Answer

The given frequency distribution doesn't look like a normal distribution, although frequencies start low, increase to some maximum, but it attain maximum quite early and then it decrease, so it doesn't look symmetric and look heavily left skewed. So, option A is correct.
