Question

What must be true about the sampling method and the values of p, q and n in order to construct a confidence interval for a proportion? [2 sentences]

Answer 1

Answer #1

we should make sure that total number of success or failure should be at least 10 for construction a confidence interval for a proportion .

Which means that np and nq both should be at least 10.
