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.

Explanation:

Identify the data values

The original graph shows the average price of a movie ticket:

• For 2009: \$7.25
• For 2010: \$7.84

Analyze the scale requirements

The question asks to draw a bar graph that shows the entire scale from \$0 to \$8.
We need to evaluate each option based on:

1. The horizontal axis scale must start at 0 and go to 8.
2. The bar for 2009 must represent \$7.25 (ending just past 7).
3. The bar for 2010 must represent \$7.84 (ending close to 8).

Evaluate the options

• Option A:
• The scale starts at 0 and goes to 8.
• The 2009 bar ends at 7.25 (just past 7).
• The 2010 bar ends at 7.84 (close to 8).
• This correctly represents the data on a full scale.
• Option B:
• The bars for both 2009 and 2010 extend all the way to 8, which is incorrect.
• Option C:
• The 2009 bar ends around 1.5 and the 2010 bar ends around 6.7, which does not match the values of \$7.25 and \$7.84.
• Option D:
• The values are swapped: 2009 is shown as longer than 2010, with 2009 ending near 7.84 and 2010 ending near 7.25.

Using Scale Distortion concepts, starting the scale at \$0 instead of \$7 provides an accurate, undistorted visual comparison of the two values. Option A is the correct graph.

Answer:

• (A) (Correct answer)
• (B)
• (C)
• (D)
