The speeds of 57 cars were measured (in km/h) on a city street. A numerical summary of the results is given below:   Descriptive Statistics: speed   Variable      N      N*       Mean        SE Mean        StDev speed           57      0          45.53         1.64                 12.38   Variable         Minimum       Q1           Median       Q3              Maximum speed               25.60               35.00       43.20            55.00        83.20   Do a calculation to decide whether the lowest recorded speed, 25.60 km/h, would be a potential outlier if drawing a boxplot by hand for this data set. What do you conclude?
