The number of story books owned by eight classmates is shown below: 8, 9, 9, 7, 8, 6, 9, 8 part a: what is the mean of the data? show your work. (4 points) part b: use your answer from part a to calculate the mean absolute deviation for the data. show your work. (10 points)

Answer: the mean is 8 and the mean absolute deviation (mad) is 0.75.to find the mean, we simply add up all the values and divide by 8. we have: 64 / 8 = 8therefore, the mean is 8.now, we have to find the mad. we subtract all of the individual values from the mean and make them positive.the values will be {0 1 1 1 0 2 1 0} if you take the mean of those values you will have: 6 / 8 0 0.75the mad of the list is 0.75.

The answer is a. point
