Question

highway fuel efficiency
how many vehicles get less than 17 miles per gallon?
14
20
25
15

Explanation:

Step1: Identify relevant intervals

Vehicles with less than 17 mpg are in intervals 1 - 8 and 9 - 16.

Step2: Find frequencies of intervals

From the bar graph, frequency for 1 - 8 is 2 (approx, since the bar reaches up to 2) and for 9 - 16 is 12. Wait, maybe I misread. Wait, looking again: the first bar (1 - 8) has frequency 2? Wait no, maybe the first bar (1 - 8) is 2, second (9 - 16) is 12? Wait no, the y - axis is frequency. Wait the first bar (1 - 8) is up to 2, second (9 - 16) is up to 12? Wait no, maybe the first bar (1 - 8) is 2, second (9 - 16) is 12? Wait no, let's check again. Wait the problem is to find vehicles with less than 17 mpg. So intervals 1 - 8 and 9 - 16 (since 17 - 24 is 17 and above). Wait the first bar (1 - 8) has frequency 2? Wait no, maybe the first bar (1 - 8) is 2, second (9 - 16) is 12? Wait no, maybe I made a mistake. Wait the second bar (9 - 16) has frequency 12, and the first bar (1 - 8) has frequency 2? Wait no, maybe the first bar is 2, second is 12, so total is 2+12 = 14? Wait no, wait the options include 14, 20, 25, 15. Wait maybe the first bar (1 - 8) is 2, second (9 - 16) is 12, so 2 + 12=14? Wait no, maybe I misread the first bar. Wait the first bar (1 - 8) is up to 2, second (9 - 16) is up to 12. So total vehicles with less than 17 mpg is frequency of 1 - 8 plus frequency of 9 - 16. So 2+12 = 14? Wait but let's check again. Wait the graph: x - axis is miles per gallon (1 - 8, 9 - 16, 17 - 24, 25 - 32, 33 - 40). y - axis is frequency. The first bar (1 - 8) has frequency 2, second (9 - 16) has frequency 12. So 2+12 = 14? But wait the options have 14 as option 1. Wait maybe that's it. Wait no, maybe the first bar is 2, second is 12, so 2 + 12=14.
Wait, maybe I misread the first bar. Let's assume that the first bar (1 - 8) has frequency 2 and the second bar (9 - 16) has frequency 12. Then total vehicles with less than 17 mpg is 2+12 = 14.

Answer:

14
