The daily sales (in thousands of shillings) of a kiosk over 7 days were 31, 30, 45, 58, 53, 25, 17. What is the mean daily sales?
Answer and explanation
Correct answer: C. 37
- Step 1: Total = 31 + 30 + 45 + 58 + 53 + 25 + 17 = 259. Step 2. Mean = 259 / 7 = 37. Answer: 37. Why not the others: 31: That is the middle value after sorting. 41: That is the range. 259: That is the total, which has not been divided by the number of days.
