consider the data set 11,12,13,14,15,16,17,18,19. complete parts (a) through (c) below. a. obtain the mean and median of the data. the mean is 15. (type an integer or a decimal. do not round.) the median is . (type an integer or a decimal. do not round.)

Answer

Explanation:

Step1: Recall median formula for odd - numbered data

For a data - set with $n$ values (where $n$ is odd), the median is the $\left(\frac{n + 1}{2}\right)$-th ordered value.

Step2: Determine the number of data points

The data set $11,12,13,14,15,16,17,18,19$ has $n=9$ values.

Step3: Calculate the position of the median

$\frac{n + 1}{2}=\frac{9+1}{2}=5$.

Step4: Find the median

The 5 - th value in the ordered data set is 15.

Answer:

15
