The table shows the number of visitors to a museum on five days.Day Visitors Mon 46 Tue 51 Wed 22 Thu 46 Fri 25
What was the mean number of visitors per day?
Answer and explanation
Correct answer: C. 38
- Step 1: Total = 46 + 51 + 22 + 46 + 25 = 190. Step 2. Mean = 190 / 5 = 38. Answer: 38. Why not the others: 46 is the median, the middle value; 36.5 is the midpoint of the highest and lowest days; 47.5 divides the total by 4 although there are five days.
