correct answer is: option c [10.5]
Explanation: First, we need to find the mean and median of the given data.
The data is: 16, 9, 12, 10, 8.
Mean: To find the mean, we sum up all the data points and divide by the number of data points.
Mean = (16 + 9 + 12 + 10 + 8) / 5 = 55 / 5 = 11
Median: To find the median, we first need to sort the data in ascending order: 8, 9, 10, 12, 16.
The median is the middle value, which is 10.
Now, we need to find the average of the mean and the median.
Average = (Mean + Median) / 2 = (11 + 10) / 2 = 21 / 2 = 10.
