Answer:
Step-by-step explanation:
Types of colours = 2 = Red and Blue
Total number of boxes sold = 1
Total no of balls = 5 + 7 + 14 + 16 + 18 =29 = 89
The statistical mean or the average is the phenomena used to derive the central tendency of the data said in the question. It is calculated by adding all the data points in a population and then dividing the total by the number of points. Thus, the resulting number is known as the mean or the average.
Thus, (89-29 /2)
= 60/2
= 30
Thus, taking the two middle values -
Also 14 + 16 = 5 + 7 + 18 = 30
