Technology Project Use Statdisk, Minitab, Excel, StatCrunch, a TI-83/84 Plus calculator, or any other software package or calculator capable of generating equally likely random digits between 0 and 9 in- clusive. Generate 5000 digits and record the results in the accompanying table. Use a 0.05 significance level to test the claim that the sample digits come from a population with a uniform distribution (so that all digits are equally likely). Does the random number generator appear to O10 9 be...
