A manufacturing firm has collected information on the number of defects produced each day for the past 50 days. The data have been described by the accompanying Minitab box-and-whisker plot.
a. What is the approximate value of the median? The first and third quartiles?
b. What do the asterisks (*) at the right of the display indicate? What implications might they have for the production supervisor?
c. Does the distribution appear to be symmetric? If not, is it positively skewed or negatively skewed?
