  • Directions for questions : Select the correct answer from the given options. The arithmetic mean of 13 observations is 60. If one of the observation 50 is deleted and another observation 63 is included. Find the new arithmetic mean. The following steps are involved in solving the above problem. Arrange them in sequential order. A New sum of observations = 780 - 50 + 63 = 793 B The sum of the observations = 13 xx 60 = 780 C therefore New arithmetic mean = (793)/(13) D The required mean = 61
