Quantile Plot 09 Refer to the data set below (body mass index of men) and determine whether the requirement of a normal distribution is satisfied. Assume that this requirement is loose in the sense that the population distribution need not be exactly normal, but it must be a distribution that is basically symmetric with only one mode. 77 74 85 80 81 Is the requirement of a normal distribution satisfied? Answer 1. Yes. The points in the normal quantile plot lie reasonably close to a straight line. 2. Yes. The points in the normal quantile plot exhibit some systematic pattern that is not a straight-line pattern. 3. No. The points in the normal quantile plot do not lie close to a straight line. 4. No. The histogram of the data is not bell shaped. There is also more than one outlier.

Question
**Quantile Plot 09** Refer to the data set below (body mass index of men) and determine whether the requirement of a normal distribution is satisfied. Assume that this requirement is loose in the sense that the population distribution need not be exactly normal, but it must be a distribution that is basically symmetric with only one mode. Data Set: - 77 - 74 - 85 - 80 - 81 **Is the requirement of a normal distribution satisfied?** **Answer** 1. □ Yes. The points in the normal quantile plot lie reasonably close to a straight line. 2. □ Yes. The points in the normal quantile plot exhibit some systematic pattern that is not a straight-line pattern. 3. □ No. The points in the normal quantile plot do not lie close to a straight line. 4. □ No. The histogram of the data is not bell shaped. There is also more than one outlier.
