प्रश्न

The width of each of nine classes in a frequency distribution is 2.5 and the lower class boundary of the lowest class 10.6. Then the upper class boundary of the highest class is

विकल्प

  •  35.6

  • 33.1

  •  30.6

  •  28.1

MCQ

उत्तर

The number of classes is 9 and the uniform class size is 2.5. The lower limit of the lower class (first class) is 10.6. Therefore, the upper limit of the last class is

`10.6 + (9xx2.5)`

=10.6 + 22.5

=33.1
