A comparison of vendor estimates of population and households with 1990 census counts in California
Abstract:
"This study compares the 1990 [U.S.] population estimates of four national demographic data vendors with the actual counts of the 1990 Census. It was performed for a consortium of three public utility companies [in California].... In addition to total population, this study evaluates the estimates of three other demographic variables...: number of households, population of Spanish origin and white population.... Differences in accuracy are found among the vendors and between variables.... On average, the estimates were most accurate for total population, considerably less so for race (white population) and households and by far the least accurate for Hispanic population."

Testing a Claim about Population Proportion
There are two methods of testing a claim about a population proportion: (1) Using the sample proportion from the data where a binomial distribution is approximated to the normal distribution and (2) Using the binomial probabilities calculated from the data.
The first method uses normal distribution as an approximation to the binomial distribution. The requirements are as follows: sample size is large...
