Answer:
The standard deviation is zero
Explanation:
Given that:
Web site W receives orders for its products every day.
What is the standard deviation of the numbers of orders that Web site W received daily for the past 5 days?
If :
(1) The average (arithmetic mean) number of orders that Web site W received per day for the past 5 days is equal to the greatest of the numbers of orders that Web site W received daily for the past 5 days.
SO, IF the average (arithmetic mean) is greatest , therefore, this implies that the number of orders per day remains the same. Then the standard deviation will be zero because the set of values for the number of orders per day for the five days is the same.( i.e contains identical numbers).
.(2) The range of the numbers of orders that Web site W received daily for the past 5 days is equal to 0.
The range is the difference between the greatest value and the smallest value.
i.e
greatest value - smallest value = 0
greatest value = smallest value
Therefore , the range is zero and the standard deviation will remain the same (zero)
