Hint: First we will use the formula of the relationship between mean, median and mode is . Then simplify the given relationship by adding and subtracting Mean on both sides to find the required value.
Complete step-by-step answer:
We know that the formula of the relationship between mean, median and mode is .
Subtracting and adding the value of mean in the above formula of relationship to find the empirical relationship, we get
Taking the 3 common from the right hand side of the above equation, we get
Therefore, the required value is .
Hence, option C is correct.
Note: We know that the mean or an average of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set. The median is the middle value when a data set is ordered from least to greatest. The mode is the number that occurs most often in a data set.
