A local school board believes there is a difference in the proportion of households with school-aged children that would support starting the school year a week earlier, and the proportion of households without school-aged children that would support starting the school year a week earlier. They survey a random sample of 40 households with school-aged children about whether they would support starting the school year a week earlier, and 38 households respond yes. They survey a random sample of 45 households that do not have school-aged children, and 25 respond yes. Let ps = the true proportion of households with school-aged children that would support startin the school year a week early and pw= the true proportion of households without school-aged children that would support starting the school year a week earlier. Which of the following are the correct hypotheses to test the school board's claim? O H,i Ps- Pw = 0; Ha' Ps- Pw>0 O Hoi Ps-Pw=0; Hgi Ps-Pw<0 O Ho: Ps-Pw= 0; Ho: Ps-Pw=0 O Ho: Ps-Pw= 0; Hoi Ps-Pw=0
