second applet.

Set mean to zero, std deviation to .8 oz

check below

enter shaded area .05

Notice the answer comes up 1.31 ounces. So the mean must be 5.3+1.31=6.61

Put that in for the mean, and verify.

You should be able to do with with your calculator also, grab your book and read. Finally, you may be learning to do this with tables...for that, hump, grunt, and strain thru it.

Hi Bob,

Thanks for the direction. I got so far with it on my own and became stuck. I did as you said but still have one question. Would the answer to the question be 1.31 ounces or 6.61 ounces? I feel the answer is 1.31. Thanks

**bobpursley**, Wednesday, October 6, 2010 at 4:56pmNo. When the mean is zero, the point comes out to be -1.31 ounces. But you want that -1.31 to be 5.3, so you add 5.3 to 1.31, mean 6.61. That way, you at 5 percent is still -1.31 ounces below the mean.

Remember here, you std deviation is .8 ounces, so three standard deviatons is only about 2.4
