Quizplus · Accepted Answer

To find the mean of a distribution, we add up all the values and divide by the total number of values. Using the table given in the question, we can calculate the mean as follows:
[(2*1)+(3*2)+(5*3)+(7*1)+(9*1)]= 29
Total number of values = (2+3+5+1+1) = 12
Mean = 29/12 = 2.42 (rounded to two decimal places)
Therefore, the best choice among the given options is C) 5.40, since it is the closest to the calculated mean of 2.42.
