Detailed Solution
Download Solution PDFFormula:
The average (arithmetic mean) of a set of values can be calculated by summing all the values and dividing the sum by the total number of values.
Average = (Sum of all values)/(Total number of values)
Solution:
Sum of values in the "P" column = 220 + 200 + 125 + 115 + 85 = 745
Average foreign trade by country P = Sum of values / Total number of years
= 745 / 5
= 149
Therefore, the average foreign trade by country P in all 5 years is 149.
