Question

Suppose a simple random sample of size n is obtained from a population whose size is N and whose population proportion with a specified characteristic is Complete parts (a) through (c) below. = 1000 = 2,000,000 p = 0.25. Click here to view the standard normal distribution table (page 1).7 Click here to view the standard normal distribution table (page 2).8 (a) Describe the sampling distribution of p. A. Approximately normal, μ and p = 0.25 σ p ≈ 0.0137 B. Approximately normal, μ and p = 0.25 σ p ≈ 0.0003 C. Approximately normal, μ and p = 0.25 σ p ≈ 0.0002 (b) What is the probability of obtaining x = 290 or more individuals with the characteristic? P(x ≥ 290) = (Round to four decimal places as needed.) (c) What is the probability of obtaining x = 230 or fewer individuals with the characteristic? P(x ≤ 230) = (Round to four decimal places as needed.)
