Answer 1

Answer - 76

Explanation:

Greetings !

First, Arrange the terms in ascending order

`66,66,68,69,69,71,74,76,77,77`

Take the upper half of the ascending set:

`71,74,76,77,77`

As, the total number of the data is 10 the half is 5.

Thus, find the median of

`71,74,76,77,77 = 76`

Median:

The median is the value separating the higher half of a data, from the lower half.

If the number of terms is odd, then the median is the middle element of the sorted set.

Hope it helps!
