Speeds of cars were measured as they passed one point on a road to study whether traffic

Question:

Speeds of cars were measured as they passed one point on a road to study whether traffic speed controls were needed. Here’s a histogram and normal probability plot of the measured speeds. Is a Normal model appropriate for these data? Explain.

20 32 15 28 24 10 20 + 15.0 22.5 30.0 -1.25 1.25 Normal Scores Speed (mph) Number of cars (ydu) paads
