### Example Question #261 : Statistics

The following graph charts the number of attendees at a theme park over the course of a year.

What is the average number of attendees from March to August, inclusive?

Explanation:

Start by figuring out how many people attended the park in those months:

 March 13000 April 15000 May 29000 June 30000 July 37000 August 26000

Recall how to find the average for a set of numbers:

Plug in the values for each of the months and divide by the number of months.

### Example Question #1 : Other Graphs

Refer to the above graph. Monique, a sixth grader at Polk, scored a 466 on the math portion of the SCAT. Which of the following could have been her rank among the students?

Explanation:

By scoring 466 on the test, Monique was outscored by the 40 students who finished in the 501-600 range, the 16 students who finished in the 601-700 range, and the 10 students who finished in the 701 to 800 range -

students.

so the highest she finished was 67th place.

She finshed among the 30 students whose scores were in the 401-500, so she was outscored by at most 29 more students - or, in all,

students.

So the lowest she finished was 96th place.

Of the five choices, the only one possible is 80th place.

The above pictograph represents the amount of chocolate eaten per person in 2014 in five countries. The legend is missing, but it is known that the average person in the United States ate 4.3 kilograms of chocolate in 2014.

The average Austrian ate 7.8 kilograms of chocolate in 2014, according to the same source. How many chocolate bars would be used to represent Austria if it were added to this pictogram?

Slightly more than three

Slightly less than four

Slightly more than four

Slightly less than three

Slightly less than four

Explanation:

The United States is represented by 2 bars of chocolate and about one-fourth of another in the pictograph, so about two and one-fourth bars represents 4.3 kilograms. Since

it would be reasonable to assume that one bar represents two kilograms of chocolate consumption per person.

7,8 kilograms would be represented by about

bars.

Slightly less than four would be the correct response.
