(1)
The mean is
Correct option is b.
(2)
Since there are 9 data values so median will be 5th data value. Median is 24.
Correct option is a.
(3)
Since there are 4 data values in first half so first quartile will be average of 2nd and 3rd data values. So,
Correct option is c.
(4)
Mode is the data value with highest frequency. Mode is 24.
Correct option is b.
(5)
Range : Maximum - minimum = 48-12=36
