Question

the following graph shows the average price of a movie ticket for the years 2009 and 2010.
complete parts (a) and (b) below.
a) draw a bar graph that shows the entire scale from $0 to $8. choose the correct graph below.
b) does the new graph give a different impression? explain. choose the correct answer below.
a. no, the price difference appears the same in the new graph.
b. yes, the price difference appears more reasonable in the old graph.
c. no, the price difference appears more reasonable in the new graph.
d. yes, the price difference appears more reasonable in the new graph.

Explanation:

Step1: Analyze the bar - graphs

A bar graph should start from \(0\) to give a proper visual representation of the differences. In the first incorrect graph (the one that doesn't start from \(0\)), the visual difference between the two bars (for 2009 and 2010) is exaggerated. When the scale starts from \(0\) (the correct bar - graph), we can accurately compare the values.

Step2: Check the price difference

The price of a movie ticket in 2009 is \(7.34\) dollars and in 2010 is \(7.95\) dollars. The difference is \(7.95 - 7.34=0.61\) dollars. In the graph that starts from \(0\) (the correct one), this small difference is represented in a more reasonable way compared to a graph that doesn't start from \(0\) (where the visual difference seems larger than the actual value difference).

Answer:

a) The correct bar - graph is the one that starts from \(0\) (let's assume it's graph A among the options).
b) B. Yes, the price difference appears more reasonable in the new graph.
