conditions for constructing a confidence interval about a difference in proportions. random. 10%. large counts. confidence interval: random. the data comes from two independent samples or from two groups in a randomized experiment. confidence interval: 10%. when sampling without replacement, check that: n1 < or = to (1/10)N.
Random Condition: The data come from a well-designed random sample or randomized experiment. 10% Condition: When sampling without replacement, check that the sample is less than 10% of the population. This allows us to use the standard deviation equation. Large Counts Condition: np 10, nq 10. This allows us to do Normal calculations.
