Answer 2

Answer: The median decreases to 77°.

Explanation:

1. First step is to order all the numbers from least to greatest.

50, 57, 58, 61, 66, 71, 77, 82, 91, 95, 100, 102, 105

2. Second step is to find the middle number

50, 57, 58, 61, 66, 71, 77, 82, 91, 95, 100, 102, 105

3. The middle number is the answer so in this case the median is now 77 which means the answer is the first choice.
