check answer
bar graph: \average travel time to work\
68 major u.s. cities\ with x-axis categories (15-19, 20-24, 25-29, 30-34, 35-39) and y-axis \absolute frequency\. source: u.s. census bureau, american community survey—average travel time to work of workers 16 hours and over who did not work at home (minutes)

Explanation:

Step1: Analyze the bar graph for 25 - 29 minutes

Look at the bar corresponding to "25 - 29" minutes in the "Average Travel Time to Work" bar graph. Estimate the height of the bar.

Step2: Compare with options

The bar for 25 - 29 minutes seems to align with a frequency around 14 (or close to the option c. 14, considering the graph's scale and the options given). Among the options (15, 20, 14, 16), 14 is the most appropriate estimate from the bar graph.

Answer:

c. 14
