what is the median?\n9.79 9.42 9.07 9.79 9.99 9.92 9.53 9.73 9.69 8.84 9.61 9.22 9.07\n8.86 8.99 9.42 9.42…

Explanation:

Step1: Arrange data in ascending order

8.84, 8.86, 8.99, 9.01, 9.07, 9.07, 9.22, 9.42, 9.42, 9.42, 9.53, 9.61, 9.69, 9.73, 9.79, 9.79, 9.92, 9.99, 9.99, 9.99

Step2: Determine the number of data points

There are $n = 20$ data - points.

Step3: Calculate the median position

Since $n$ is even, the median is the average of the $\frac{n}{2}$th and $(\frac{n}{2}+1)$th ordered data values. $\frac{n}{2}=\frac{20}{2}=10$ and $\frac{n}{2}+1 = 11$.

Step4: Find the median

The 10th value is 9.42 and the 11th value is 9.53. The median is $\frac{9.42 + 9.53}{2}=\frac{18.95}{2}=9.475$

Answer:

9.475
