Chapter 11, Problem 1TP
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 inclusive. 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 be working as it should?
| Digit | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 |
| Frequency |
| Statdisk: | Select Data, then Uniform Generator. |
| Mini tab: | Select Calc, Random Data, Integer. |
| Excel: | Click Insert |
| TI-83/84 Plus: | Press MATH, select PROB, then use randlnt function with the format of randInt(lower, upper, n). |
