a)
Mean =
Arranging in ascending order:
8.5, 13.2, 15.8, 15.9, 21.8
Since the number of observations is odd, so Median =
b)
Mean =
Arranging in ascending order:
8.5, 13.2, 15.8, 15.9, 21.8, 32.6
Since the number of observations is even, so Median =
c)
Adding the new state increased the value of the mean by a greater margin as compared to increase in the value of the median.
Hence mean is more susceptible to extreme values.
