Why is it necessary to check that np 25 and nq 25? O A. It is necessary to check that np25 and nq 2 5 to be certain that the minimum value of the sample size, n, is met. O B. It is necessary to check that np 25 and nq 25 because, if either of the values are less than 5, the tails on either side of the left and right endpoints are not accounted for. O C. It is necessary to check that np 2 5 and ng 25 because, if either of the values are less than 5, the distribution may not be normally distributed, thus z, cannot be used to calculate the confidence interval. O D. It is necessary to check that np 2 5 and ng 25 because the confidence intervals estimating the population proportions will overlap if these values are less thar 5.
