Question: Random digits. We know that the proportion of 0s among a large set of random digits is p = 0.1 because all 10 possible digits are equally probable. The entries in a table of random digits are a sample from the population of all random digits. To get an SRS of 200 random digits, look at the first digit in each of the 200 five-digit groups in lines 101 to 125 of Table A in the back of the book. How many of these 200 digits are 0s? Give a 95% confidence interval for the proportion of 0s in the population from which these digits are a sample. Does your interval cover the true parameter value, p = 0.1?
