Answer

It would be appropriate to apply the normal model here.

Work Step by Step

To apply the normal model, the data must be unimodal, mostly symmetrical, and approximately normal. -The histogram indicates that the car speed data is unimodal and approximately symmetrical. -The boxplot indicates that the data is mostly symmetrical. -The normal probability plot shows a straight line, meaning that none of the points deviate substantially from normality. So, since the data is unimodal, symmetric, and approximately normal, the normal model can be applied.
