0 Question 17 E 0/1 pt '0 4 U) Details 5",: Comments I This test is commonly known as the z ~test for the population proportion. 0 When we take a random sample of size n from a population with a population proportion p , the possible values of the sample proportion (13) (when certain conditions are met) have 1 9 approximately a normal distribution with a mean of p and a standard deviation of p( n ) . To use this test, the following conditions need to be bet: 1. The sample has to be random. 2. The conditions under which the sampling distribution off) is normal are met. In other words: n-pD>10 n'(1po)210 ? Question We are conducting a survey to determine if an upcoming bond measure will receive a majority vote in the county. The null hypothesis claims thatp = 0.50 , where p is the proportion of registered voters in the county who say they support the bond measure.
