Want to know:

1. the normal curve= symmetric about the mean2. because mean= median= mode, the normal curve has a single peak and the highest point at the mean 3. the shape of the normal curve is determined by its SD4. the normal curve has inflection points at M-SD and M+SD (1SD above and below the mean)5. the area under the normal curve is 16. the area under the normal curve to the right of the Mean = the area under the curve to the left of Mean, which equals 1/27. as x increases without bound, the graph approaches but never reaches the horizontal axis. as x decreases without bound, the graph approaches but never reaches the horizontal axis
