Question

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 starting 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 is the correct standardized test statistic and P-value for the hypotheses, ?

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 is the correct standardized test statistic and P-value for the hypotheses, H,: p,-Pw=0 and H, P,-Pw =0? Find the z-table here. 0.95 – 0.56 (0.26)(0.74) O = P- value = 0.000017 95 0.95 - 0.56 O z= ,P- value = 0.000017 (0.74)(0.26) , (0.74)(0.26) + 95 45 0.95 - 0.56 O z = ,P – value = 0.000034 (0.95)(0.0.05) (0.56)(0.44) 40 45 0.95 - 0.56 O z = ,P- value = 0.000034 (0.74)(0.26) , (0.74)(0.26) 40 45
