Answer:
George should use "Average" to compute the expected number of guests.
Explanation:
Average is computed to find the central value of some given values to know the overall behavior of some particular event.
<u>For Example</u>
A student has 5 courses in a class, He got different marks in all the courses, to find his overall performance, average has been computed to find the overall behavior of the student. The Average value of marks rate the student in terms of overall performance.
In given case, George have list of No. of Guest who attended their last event. To find the expected number for Guest for his current Birthday, He observes the data and find the average No. of guest. Which means Guest are nearly to the Average value with a small margin.
