Question

How long does it take you to get from home to work? Here are the travel times in minutes for 15 workers in North Carolina, chosen at random by the Census Bureau. 30 20 10 40 25 20 10 62 15 40 5 30 11 10 10 The mean travel time of the 15 North Carolina workers is given below. x? = (x1 + x2 + ... + xn) / n = (30 + 20 + ... + 10) / 15 = 338 / 15 = 22.5 minutes Notice that only 6 of the 15 travel times are larger than the mean. If we leave out the longest single travel time, 62 minutes, the mean for the remaining 14 people is minutes. That one observation raises the mean by minutes. Does the 1.5 !!! IQR rule identify this travel time as a suspected outlier? The 1.5 !!! IQR rule cannot be determined. This travel time is identified as an outlier. This travel time cannot be determined. This travel time is not identified as an outlier.
