answer attempt 2 out of 2
median =
mean =
submit answer

Explanation:

Step1: Sort the data set

$0, 2, 9, 15, 19, 21, 39$

Step2: Find the median

Since there are 7 (odd) values, the median is the 4th value: $15$

Step3: Calculate sum of data

$0 + 2 + 9 + 15 + 19 + 21 + 39 = 105$

Step4: Compute the mean

$\text{Mean} = \frac{\text{Sum of data}}{\text{Number of data points}} = \frac{105}{7} = 15$

Answer:

Median = 15
Mean = 15
