Respuesta :

group a because they have a lower mean. and from the information above the dots represent the amount which is smaller
The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words, it is the sum divided by the count.

Group A= 15+40+102+96+84= 337 so then 337 divided by 5 (the amount of groups of dots) would be = 67.4

Now that you know how to do part A, ill let you try and do part B by yourself. if you need any more help, just ask and I won't mind helping.
