In each of the following cases, determine if the sample sizes are large enough so that the sampling distribution of the differences in the sample proportions can be approximated with a normal distribution. complete parts a through d below. a. suppose n 1equals30, n 2equals44, x 1equals16, and x 2equals43. choose the correct answer below. a. the sampling distribution of the differences in the sample proportions can be approximated with a normal distribution because n 1 p overbar 1 and n 2 p overbar 2 are less than 5. b. the sampling distribution of the differences in the sample proportions cannot be approximated with a normal distribution because n 2 left parenthesis 1 minus p overbar 2 right parenthesis is less than 5. nothing c. the sampling distribution of the differences in the sample proportions can be approximated with a normal distribution because n 2 left parenthesis 1 minus p overbar 2 right parenthesis is greater than or equal to 5.
