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 function fx, then select category Math & Trig and function RANDBETWEEN. Click and drag cell down the column to generate additional random numbers.
TI-83/84 Plus:	Press MATH, select PROB, then use randlnt function with the format of randInt(lower, upper, n).
StatCrunch:	Select Data, Simulate, Discrete Uniform.
