Question 1

Which of the following is not a method used for determining whether data are from an approximately normal distribution?
◦ Compute the intervals ± s, ± 2s, and ± 3s. The percentages of measurements falling in each should be approximately 68%, 95%, and 100% respectively.
◦ Construct a normal probability plot. The points should fall approximately on a straight line.
◦ Construct a histogram or stem-and-leaf display. The shape of the graph or display should be uniform (evenly distributed).
◦ Find the interquartile range, IQR, and standard deviation, s, for the sample. Then ≈ 1.3.

Question 2

Which one of the following suggests that the data set is approximately normal?
◦ A data set with Q1 = 2.2, Q3 = 7.3, and s = 2.1.
◦ A data set with Q1 = 105, Q3 = 270, and s = 33.
◦ A data set with Q1 = 1330, Q3 = 2940, and s = 2440.
◦ A data set with Q1 = 14, Q3 = 68, and s = 41.
