Answer: B - A research survey taken of female Reebok users shows an average use of 12.8 hours per week with a standard deviation of 1.5 hours. One of the survey results shows a figure of 32 hours, which is considered an outlier. An outlier figure in a survey such as this one is considered a figure that is numerically distant from the remainder of the data. Given the average and standard deviation of Reebok use, this figure is clearly an outlier and may have occurred by chance. Outliers can also occur due to an error of measurement methodology or instrumentation.
