The use of the standard normal distribution for constructing a confidence interval estimate for the population proportion pp requires:A. np^np^ and n(1−p^n(1−p^) are both greater than 5, where p^p^ denotes the sample proportionB. that the sample size is greater than 30C. npnp and n(1−p)n(1−p) are both greater than 5D. n(p+p^)n(p+p^) and n(p−p^)n(p−p^) are both greater than 5 Under which of the following circumstances is it impossible to construct a confidence interval for the population mean?A. A non-normal population with a small sample and an unknown population variance.B. A normal population with a small sample and an unknown population variance.C. A normal population with a large sample and a known population variance.D. A non-normal population with a large sample and an unknown population variance.
