It can only be due to an error of recording the values.</em> It suppose to be recorded as 49.1.

b) Since this was a sample of annual income of five different families, it quite possible that a particular family annual income is $1, 200, 000. Hence, we cannot regard this outlier an error, rather conceivably true.
