On the left side, you will have b squared.
On the right side, you will have 1/4.
Now, take the square root of both sides.
The square root of 1/4 is positive or negative 1/2.

Answer: 85.5
Step-by-step explanation:
There are 22 data points in the data set.
We can find the median by looking at the 11th and 12th scores, and averaging them.
