a) 64 kg
b) 65 kg
c) 66 kg
d) 67 kg

Answer :

Final answer:

The median of the given data set of weights is (b) 65 kg.

Explanation:

The median is the middle value when the data is ordered from smallest to largest.

  1. First, order the weights from smallest to largest: 59, 60, 61, 62, 62, 63, 63, 64, 64, 64, 65, 65, 65, 65, 65, 65, 65, 65, 65, 66, 66, 67, 67, 68, 68, 69, 70, 70, 70, 70, 70, 71, 71, 72, 72, 73, 74, 74, 75, 77.
  2. As there are 40 values, the median will be the average of the 20th and 21st values, which are both 65.
  3. Therefore, the median of the data is 65 kg (option b).
