a) Mean = (260 + 270 + 180 + 187 + 303 + 210 + 298 + 309 + 180 + 181 + 298)/11
= 243.3 pounds
b) Data in ascending order : 180, 180, 181, 187, 210, 260, 270, 298, 298, 303, 309
There are 11 terms
Median is (n+1)/2 th term = (11+1)/2 = 6th term
Median = 260 pounds
c) A. The modes are 180, 298 pounds
d) Mid range = (180 + 309)/2
= 244.5 pounds
e) The measures of central tendencies are not approximately equal. The sample is not representative of population. The sample is drawn from a cluster within the population. So, we cannot say that the sample is representative of all the players in that sports league
