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.
