In my Geometry class, we were going over Statistics and stuff like Standard Deviation. Only thing was that I missed the lesson becaus eof being in the Hospital with my brother. I have a test on it tomorrow and need help! Can someone with good knowledge of Math, tell me how to make a regular Histogram using data Points and the Standard Deviation? I know what I HAVE to do, I just can't get started doing it. (I'm looking for a kinda quick explanation, not some 30-page one please.)

I don't know if this is what you're looking for, but it may help, or at least get you going in the right direction.

Thanks for the links, but it's not quite what I was looking for... Here's a sample question for what I have to do:
A survey was taken of High School students about their ACT scores. The mean ACT score was 20 and the standard deviation was 3. Use this info to answer the following Questions:

A. Draw the normal distribution of this data

B. Find and then label the three standard deviation ranges on the graph

C. Draw the percents that the standard deviations represent on the graph.

D. What percent of the Students have an ACT between 14 and 26

E. What percent of the students scored better than 23?

F. What percent of the students scored between 17 and 26

G. What percent of the students scored between 17 and 26

H.What percent of the students scored below 14

I. What is the probability of meeting a student that scored above 26

J. What is the probability of meeting a student that scored below 20

I have no choice but to take it today because we're getting ready to start Finals, so I need major help now...

Ok, try this instead. Has examples very similar to yours and explains the process and answers.

I was just about to suggest the same site. The "Ask Dr. Math" articles are one of the best math resources I've ever come across. You can search for your problem and get a quick answer and explination for it.
