Homework: Extra credit Assignment (Worth 3 pts to overall co Save 57 of 67 (62 complete) Score: 0.33 of 1 pt &8.2.7 Describe the sampling distribution of p. Assume the size of the population is 30,000 HW Score: 85.52%, 57.3 of 67 pts Question Help * n 900, p 0.7 Choose the phrase that best describes the shape of the sampling distribution of p below A. Approximately normal because ns0.05N and np(1-p)2 10. 0 B. Not normal because n 0.05N and np(1-p)2 10. O c. Approximately normal because n s 005N and np(1-p)
