 Hi folks this is Don. This is a problem that you can solve very quickly using the normal calculator and stat crunch. 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 stat crunch. We're going to bring up stat crunch here. We go to stat, calculators, normal, bring up our dialog box. In this case we want to click on the between tab and we get our standard normal curve. This on our curve of course the area is shown in red. We need to change our lower limit from minus one to minus one point four. We can leave our upper limit at one, click on compute, and we get an area under the curve of point seven six one. I guess if you rounded it off I guess they want five decimal places four decimal places so it's point seven six zero six. A little bit different from theirs. But that's how fast you can solve it.
