What is the probability that a loaf of bread is < 20.75

**Ashley**, Tuesday, March 30, 2010 at 8:50pmThe first thing you have to do is find the z score. z=(20.75-22)/.5 The z would be -2.5 Then, to find the probability, you can use your graphing calculator. Hit 2nd, then catalog, then go down to normalpdf. When that comes up, plug in -2.5 and it should give you a probability of .0175.

Hope that helps!

**PsyDAG**, Wednesday, March 31, 2010 at 1:44pmIf you don't have a graphing calculator, you can find table in the back of your statistics text labeled something like "areas under normal distribution" to find the probability.

I hope that helps a little more.
