Remember, that the mean is calculated by adding up totals and dividing the total by the number of scores.
In this case, we would add the weight's of the 6 cats which is 62 (14+12+8+12+11+5).
Now we divide the total weight (62) by the number of cats (6).
62/6 = 10.3333333333
Now round to the nearest tenth 10.3.
The mean weight of the cats is 10.3 pounds.
