To test the effectiveness of certain computer software's random number generator, 1 randomly select 1000 numbers form a standard Normal distribution. I classify these 1000 numbers according to whether their values are at most -2, between -2 and 0, between 0 and 2 or at least 2. The results are given in the following table. The expected counts, based on the 68%-95%-99.7% rule are given as well. Observed count Expected count At most-2 Between-2 and 0 Between 0 and 2 18 492 468 25 475 475 At least 2 22 25 The p-value of the test is less than 0.10
