 Hi folks, this is Don. This is a problem that you can solve very quickly using the normal calculator in StatCrunch. The problem is that you need to find the area between minus 1.4, a z of minus 1.4, and a z of plus 1 on the standard normal curve. Now of course you can use the standard normal tables and you need to know how to do that, but once you do try using StatCrunch. We're going to bring up StatCrunch here and we just go to StatCalculators Normal, bring up our little dialog box. We want to click on the Between tab and we get our standard normal curve and we can see the area now is between minus 1 and plus 1. We want minus 1.4, so I put that there. I'm going to leave the 1 in there and click Compute and we get an answer of 0.76. That's how fast you can solve it.
