Team A 16, 13, 12, 16, 13
The mean is:
The standard deviation is:
Team B: 10, 13, 16, 16, 10
The mean is:
The standard deviation is:
Which statement appropriately compares the ages of the team members?
Sample of team A has higher mean age, which means that they are likely older. They also have a smaller standard deviation, so they likely have less variability in their ages.
