उत्तर

The given distribution is discontinuous.

Lower boundary = lower limit – `1/2` ...(gap between the adjacent class interval)

= `50 - 1/2` (1) = 49.5

Upper boundary = Upper limit + `1/2` ...(gap between the adjacent class interval)

= `55 + 1/2` (1) = 55.5

∴ The continuous frequency table is as below.

Weight (in kg) 49.5 − 55.5 55.5 − 61.5 61.5 − 67.5 67.5 − 73.5 73.5 − 79.5 79.5 − 85.5 85.5 − 91.5
