Question

A survey of 9 adults employed full-time was taken. Here are their reported numbers of hours worked per week: 49,54,37,48,42,41,36,45,47 what is the mean,media and mode?

Answer 1

The given data are :

$49,54,37,48,42,41,36,45,47$

At first, make the data in order from the least to the greatest

$36,37,41,42,45,47,48,49,54$

Mean is the average of the data

Mean = (sum of the data)/(number of the data)

Sum of the data =

$36+37+41+42+45+47+48+49+54=399$

The number of the data = 9

So,

$\text{Mean}=\frac{399}{9}=44\frac{1}{3}=44.33$

Median is the number which is in the middle of the data

We have 9 data

So, the median is the number (9+1)/2 = 10/2 = 5

So,

$\text{Median}=45$

Mode is the data which is repeated more than the others

So, when we looking to the data, each number appeared one time

So,

There is no mode
