Question 419959
A study of motor vehicle rates in the 50 states reveals that traffic death rates (deaths per 100 million motor vehicle miles driven) can be modeled by the normal curve. 
------------------------------------------------
The data suggest that the distribution has a mean of 5.3 and a standard deviation of 1.3. Sketch the normal curve, showing the mean and standard deviation.
---
Sketch the curve. (Use Google if you do not know what a normal curve 
looks like.)
--
Put the mean value on the base line in the middle of the curve.
---
Mark a point 1.3 to the right and another 1.3 to the left of 5.3.
---
Each of those points is about 1/3 the distance from the center to
the tail of the curve.
