A data set lists the number of hours waiters worked at a restaurant every Friday during the last year. For this data set, the minimum is 1 , the median is 5 , the third quartile is 8 , the interquartile range is 4 , and the maximum is 17 . Construct a box-and-whisker plot that shows the number of hours worked on a Friday. Begin by first placing the middle dot on the median. Then work on placing the rest of the points starting with the ones closest to the median.
