Now let's try a normal distribution. The first plot will be easy, but the second will be more difficult to do, so follow the instructions carefully. First we'll plot a standard normal, then we'll see what happens if you change the parameters. x <- seq (-3.291, 3.291, length.out=100) gives us 100 equally spaced values of x between -3.291 and 3.291. “seq” let's us generate a sequence of numbers, and “length.out” tells us how many numbers we want in the sequence....
