Question

4. You take a simple random sample of size 25 from a very large population in which the true proportion is p=0.1. Which statement below best describes what you know about the sampling distribution of p? 0.1(0.9) (a) Mp -0.1;0p , the distribution is skewed right. 0.1(0.9) (b) Mp -0.1; 0- 25 ; the distribution is skewed left. (c) Mp - 0.1; 0 ; the distribution is approximately Normal. (d) Mp = 0.1; we can not use the formula Op 0.1(0.9) 25 2: the distribution is not approximately normal pe 10 1(0.9) (e) Mp -0.1; we can not use the formula Op the distribution is approximately normal.
