Extracted text: Calculating Sample Statistics 2. Listed are head injury measurements from small cars that were tested in crashes. The measurements are in "hic," which is a measurement of a standard "head injury criterion," (lower "hic" values correspond to safer cars). Find the mean, variance, standard deviation, median, range, midrange, mode and coefficient of variation for the data. Round decimals to two places.
