Carla runs for exercise several days each week. The number of miles she ran each week for the last 6 weeks is shown below.
10, 9, 8, 14, 9, 12
Which is a reasonable prediction of the mean number of miles Carla runs each week throughout the year?
14
13
12
10
To find the mean number of miles Carla runs each week throughout the year, we add up the total number of miles she ran over the past 6 weeks and divide by 6 (the number of weeks).
10 + 9 + 8 + 14 + 9 + 12 = 62
62 / 6 = 10.33
Therefore, a reasonable prediction of the mean number of miles Carla runs each week throughout the year is 10.
