The distribution of travel mileage in a courier service is multimodal with a long right tail. Would a simple random sample of 20 trips work well for estimating the true mean mileage? Yes, if the distribution is normal and statistically significant. O No, as travel is a qualitative variable measured by a proportion. O Yes, if there are over 5 long trips and over 5 short trips. O No, as the sample size should exceed 30 for skewed distributions.
