This question refers to the graph below, which shows admissions to a hospital during a given week. What was the average number of admissions over Friday, Saturday, and Sunday?

Rationale

The average number of admissions over Friday, Saturday, and Sunday was 40.

To find the average, you add up the total number of admissions for those three days and then divide by the number of days.

A (36) YOUR ANSWER

This choice might have been calculated by incorrectly averaging the number of admissions over the entire week, or by misreading the graph. The correct average for Friday, Saturday, and Sunday is higher than this.

B (37) YOUR ANSWER

This choice might be the result of a minor calculation error when adding up the total admissions for the three days and dividing by three. It is close to the correct answer but not quite accurate.

C (40) CORRECT

This is the correct answer. The total number of admissions for Friday, Saturday, and Sunday, divided by three, equals 40.

D (43) YOUR ANSWER

This choice might have been reached by miscalculating the total number of admissions for the three days or by dividing by a smaller number than the correct divisor of three.

Conclusion

The average number of admissions to the hospital over Friday, Saturday, and Sunday was 40. The other choices represent calculations that do not accurately reflect the average admissions for these three days based on the data provided in the graph. Understanding how to correctly calculate averages from graphical data is essential for accurate data interpretation.
