Question TO Question 10 2 points Save Answer A local car manufacturer is looking to introduce a new model of car but is uncertain if they should produce a hatchback or an SUV. They conducted market research to see what kind of cars are preferred by asking 302 people. 89 indicated that they like hatchbacks and dislike SUVs, 89 indicated they like both hatchbacks and SUVs, 190 dislike SUVs.

They ride their bike to the train station, catch the train and finally take the bus to Uni. They notice that their average speed varies. On their bike they travel at 27.6 km/h, on the train portion they average 65 km/h, and the bus they catch averages 41.9 km/h. They usually spend 18.5 minutes on their bike, 20 minutes on the train and 7.5 minutes on the bus, in total taking 46 minutes to get to Uni.
