The Correct Option is C
Solution and Explanation
First add up all seven monthly readings:
10337.68 + 10631.12 + 10120.01 + 9734.22 + 9964.29 + 10536.16 + 9839.69 = 71163.17.
Divide by 7 to get the average: \(\dfrac{71163.17}{7} \approx 10166.17\).
Now compare each month's reading to this average of 10166.17:
May 10337.68 - above average
June 10631.12 - above average
July 10120.01 - below average
August 9734.22 - below average
September 9964.29 - below average
October 10536.16 - above average
November 9839.69 - below average
Four months (July, August, September, November) fall below the average, so the answer is 4, option (c).
10337.68 + 10631.12 + 10120.01 + 9734.22 + 9964.29 + 10536.16 + 9839.69 = 71163.17.
Divide by 7 to get the average: \(\dfrac{71163.17}{7} \approx 10166.17\).
Now compare each month's reading to this average of 10166.17:
May 10337.68 - above average
June 10631.12 - above average
July 10120.01 - below average
August 9734.22 - below average
September 9964.29 - below average
October 10536.16 - above average
November 9839.69 - below average
Four months (July, August, September, November) fall below the average, so the answer is 4, option (c).
