Answer» d Answer:-When any two of the measure of central tendency:MeanMedianModeIs provided to us, we can use the empirical relation between them to FIND the third one. The relation is:Plugging the values of MEDIAN and Mode in the above formula to find the mode:⇒ 3 × 42 - 2 × MEAN = 47⇒ 2 × mean = 126 - 47⇒ 2 × mean = 79⇒ mean = 79 / 2⇒ mean = 39.5Hence:-The mean of the given data is 39.5 (C) |
