P: a) For the shape of the distribution of the sample proportion to be approximately normal, it is required that npci-d) > 10). b) suppose the proportion of the population that has a certain characteristic is 0165. The mean of the sampling distribution of Ê from this population is up = 0.65] - 9. According to a study conducted by statistical organisation, the proportion of people who are satisfied with the way things are going in their lives is 0172. suppose that a random sample of too is obtained. c) sampling distribution of Ê since the sample size is more than 5% of the population size & np (1-P) - 2016 >10 the distribution of ê is normal with 4 § - 6:72 and 1 o Ⓡ =PCrp) -0.04489 100 Q 0 - 200, P=0.5, N20,000 Sampling distribution of ² Approximately nomal because o SO5N np clap) > 10 je 2005 10000) & 507,10) up = 0.5 =P + h - 200 NE 30,000, P-0.8 Appooximately normal because n sous N & npC1-p]=10 (lie 200 = 15000 & 32 >10 ) up = p = 0.8
