Find the mean.
$$12.45 , 12.99 , 10.50 ,11.25 , 9.99 , 12.72$$
Therefore, the mean is 11.65
in this problem, we're going to find the meaning of this set of numbers. And the main is the sum of the values divided by n where n is the number of values. So in this that we have six values. So in a six, so the mean will be the sum of all these numbers divided by six. And when you add all these numbers together you get 69.9, 69.9 divided by six is 11.65 This seems like a reasonable mean because it does fall between the lowest value of 10.5 and the highest value of 12.99
