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
