SITUATION 1
Direct evidence of Newton's universal law of gravitation was provided from a
renowned experiment by Henry Cavendish (1731-1810). In the experiment, masses
of objects (treated as samples) were determined by weighing, and the measured force
of attraction was used to calculate the density of the earth, The values of the earth's
density (in g/cm), in time order by row, are:
5.39
5.26
5.55
5.68
5.53
5.57
5.69 5.22
5.44
5.34
5.70
5.19
5.29
5.37
5.47
5.42
5.64
5.33
5.45
5.30
5.76
5.65
5.88
(a) Determine the mean, median, range, variance, standard deviation, and coefficient
of variation of the given data set.
(b) Evaluate if the data set is symmetric, positively skewed, or negatively skewed.
Justify your answer.
(c) Evaluate if the kurtosis of the given data set is mesokurtic, leptokurtic, or
platykurtic. Justify your answer.
