Question

5. Calculate the Mean, Median and mode for the following distribution. Verify the empirical formula 20-30 60-70 70-80 Class Interval Frequency 0-10 6 10-20 10 30-40 15 40-50 20 50-60 12 13 10 8​

Answer 1

Answer:

Correct option is A)

To find the median class:

First add the total number of frequencies.

Here, f=93

=

2

(Totalnumberoffrequency)

=(93)/2=46.5

Hence, the value 46.5 lies in the class interval 30-40 from the cummulative frequency table.
