Answer

Explanation:

Step1: Determine the number of data points

There are $n = 30$ data - points.

Step2: Find the position of the median

Since $n = 30$ (an even number), the median is the average of the $\frac{n}{2}=15$th and $(\frac{n}{2}+1) = 16$th ordered data - points.

Step3: Identify the 15th and 16th data - points

The 15th value is 19 and the 16th value is 19.

Step4: Calculate the median

Median=$\frac{19 + 19}{2}=19$

Answer:

19
