Amount of time for company 2: 6, 32, 9, 31, 21
Amount of time for company 3: 15, 15, 15, 15, 15
Amount of time for company 4: 13, 10, 45, 12, 15
 based on the data, which company most likely has the longest average commute time per employee?

(Please help me, i don't understand what they're trying to say)

Answer 1

Its company 1. if you find the means of all of the company's, company 1 has the biggest mean which means they have the longest commute. So the answer is company 1

Answer 2

Answer:

Company 1 most likely has the longest average commute time per employee.  

Step-by-step explanation:

A researcher surveyed five randomly selected employees from each of four different companies about their daily commutes to work.

We have to find which company most likely has the longest average commute time per employee.

So we will find the mean of the given each company's data

Mean = Sum of total number /total number of values

For Company 1 :  $\frac{24 + 26 + 28 + 23 + 21 }{5}$ = 24.4

For company 2 : $\frac{6+32+9+31+21}{5}$ = 19.8          

For company 3 :  $\frac{15+15+15+15+15}{5}$ = 15                      

For company 4 : $\frac{13+10+45+12+15}{5}$ = 19    

As we can see Company 1 has largest mean.

So Company 1 most likely has the longest average commute time per employee.
