Answer 2

The mean of the data is 26.25.

Step-by-step explanation:

Since we have given that

Class         Frequency(f)       Mid point (x)            fx

0-20                6                        10                        60

20-40              7                        30                       210

40-60              3                        50                       150

----------------------------------------------------------------------------------------

                      16                                                     420

So, Mean would be

$\bar{x}=\dfrac{\sum fx}{\sum f}\\\\\bar{x}=\dfrac{420}{16}\\\\\bar{x}=26.25$

Hence, the mean of the data is 26.25.
