Consider a situation in which sampling without replacement is used to generate a random sample from each of two separate populations. To calculate a confidence interval to estimate the difference between population proportions, which of the following checks must be made? A) Each population must be at least 10 times as large as its corresponding sample. в Both populations must be approximately normal. The data from both samples must unimodal, symmetrical, and approximately normal. D Each sample proportion value must be less than or equal to 0.5. The sample sizes must be the same.
