A psychologist is gathering data on testosterone levels on a sample of 100 college students living in India. None of the values are less than zero (because humans cannot produce negative levels of testosterone), but the sample reveals there are several outliers more than 3 standard deviations above the mean. The psychologist concludes that the distribution of the values is highly left-skewed.
