Answer:

B) 70.5

Explanation:

Median = middle value when the values are placed in order.

If there are two middle values, the median is the mean of those two values.

Class 1

45 46 51 52 53 53 61 63 64 65 66 68 70 70 71 73 76 77 79 81 82 83 84 87 90 92 93 95

There are 28 values in Class 1.

Therefore, there are two middle values: 14th and 15th values

14th value = 70

15th value = 71


\implies \textsf{Median}=(70+71)/(2)=70.5
