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.
