Is it possible to graph a curve based on descriptive statistics in Excel?
For example:
mean: 8.147
standard deviation: 0.142
Assuming a normal curve, I am told that I can graph this, but I don't believe it's possible with Excel.
That is, I can do the following: generate a random number set with a normal distribution, then create a histogram.

What I'd like to do is create a continuous line curve of the kind you see in textbooks, to illustrate rejection regions and critical values, etc. I suspect I'll need to look into some other software package or browser-based statistical application but before I say good bye to Excel on this I thought I'd check here.
Cheers

(note - in anticipation of a statistics class next year where there will be a lot of hypothesis testing for the first section. I sort of blew it in the first half of the course by just drawing all my graphs by hand, much to my prof's "delight").
