1. For the following data set, representing a sample, Find a:
the mean, median, mid-range, mode, first quartile, second quartile,
third quartile, interquartile range, and draw a box plot. b: the
variance, and standard deviation, using the shortcut formula, and
the range. c: the percentile rank of 9, and the value corresponding
to the 60th percentile. d: the z-score of 6, if the mean is 7 and
the standard deviation is 2.2. (75 pts.)
