Answer :

Answer:

mean = 31.4

Step-by-step explanation:

The mean of a group of values is calculated as

• mean = ( sum of values ) ÷ ( number of values )

given the number of values is 5 , that is

18 , 18 , 33 , 34 , 54

sum = 18 + 18 + 33 + 34 + 54 = 157

Then

mean = 157 ÷ 5 = 31.4

Answer:

31.4

Step-by-step explanation:

To calculate the mean you have to add the numbers to find the total and then divide that answer by the number of variables.

So we would do:

1. 18 + 18 + 33 + 34 + 54 = 157

2. 157 ÷ 5 = 31.4

(We divide by 5 because that's how many numbers we added to get the total)
