Step-by-step explanation:We know that,

## Range=(Largest observation-Smallest observation)

## So,

## Range=50-32=18

We know that,

## After rearranging the given observations in ascending order,If the number of observations(n) is odd,

## So,In ascending order,the observations

are

## 32,35,36 ,37, 38, 38, 38, 40 ,42 ,43, 43, 43, 45, 47 ,50

Since,there are 15 observations in total,

## So,

## The 8 th term from beginning is 40.

## Hence,

## 40 is the median of the given data.
