1. 2.
Why is it necessary to check that np 25 and nq 25? ^ O A. It is necessary to check that np 25 and nq 25 to be certain that the minimum value of the sample size, n, is met. OB. It is necessary to check that nộ 25 and nĝ 5 because the confidence intervals estimating the population proportions will overlap if these values are less than 5. O C. It is necessary to check that np...
