4.7 Random digits.
As discussed in Chapter 3, generation of random numbers is one approach for obtaining a simple random sample (SRS). If we were to look at the random generation of digits, the mechanism should give each digit probability 0.1. Consider the digit “0” in particular.
Based on the software you used, what proportion of the 1000 randomly generated digits are 0s? Is this proportion close to 0.1?
4.7
(a) 0.105. (b) Answers should be close to 0.1.
