Explanation & Answer

The solution is attached.Let me know if you need any clarification.

Part 1
Mean is the arithmetic average of all the values in a given dataset. The mean is computed by
dividing the sum of the values in a dataset by the number of items in the dataset.
Median: The median is the middle value in an ordered set of number. To find the median of a
given set of number, arrange the number in ascending or descending order than identify the
number that splits the whole set of numbers into two equal groups.
Mode: For a given set of values, the mode is the value with the highest frequency, i.e. the value
that occurs the most in the dataset.

Part 2
The mean is 216.8
The median is 206
The mode is 187
