The data gives the weight for 15 corn cobs (displayed in ascending order) which were produced using an organic corn fertilizer:

169, 192, 200, 202, 204, 214, 216, 231, 232, 234, 237, 243, 246, 260, 262

Note that ??Σ??i=115 = 3342.0 and ??Σ??i=115 xi2 = 754216.0, where xi is the weight of the ith corn cob for i=1,2...15

a) For this random sample of n=15 observations, obtain the mean, the median, the interquartile range and the standard deviation.

b) Among the 4 statistics is part a), which are measures of central tendency and which are measures of dispersion?
