A study was conducted to determine the effectiveness of a speed limit sign. The speeds of cars at the 65 mph sign were: 58 60 65 65 70 70 71 74 85 88 Which box plot correctly displays the information? (1 point) Responses A A B B C C D D Skip to navigation
The correct box plot displaying the speeds of cars at the 65 mph sign would have the following characteristics:
- The median speed would be around 70 mph, as there are an equal number of speeds above and below this value.
- The lower quartile (Q1) would be around 65 mph, as this is the speed that separates the lower 25% of speeds from the rest.
- The upper quartile (Q3) would be around 74 mph, as this is the speed that separates the upper 25% of speeds from the rest.
- There would be some outliers at higher speeds, such as 85 and 88 mph.
Based on these characteristics, the correct box plot would be Graphic C.
