10.50 5.70 14.67 9.50 12.54
8.90 13.56 11.23 6.80 3.00 10.55
Find the mean amount spent by these customers.

Respuesta :

Answer:  9.83

Explanation:

The first step is to add up all the values given:

11.01 + 10.50 + 5.70 + 14.67 + 9.50 + 12.54 + 8.90 + 13.56 + 11.23 + 6.80 + 3.00 + 10.55 = 117.96

Then we divide this sum over n = 12 since this is the sample size given (i.e. the number of customers)

117.96/n = 117.96/12 = 9.83
The answer is $9.83.
I hope this helps!
