In a public opinion survey, 60 out of a sample of 100 high-income voters and 40 out of a sample of 75 low-income voters supported a decrease in value-added tax, VAT. Conclude at the 5% level of significance that the population of voters favouring a VAT decrease differs between high- and low-income voters. (Where p1 is the proportion of all high-income voters who supported a decrease in VAT; p2 is the same for the low-income voters). The hypotheses are:   A. H0: p1 - p2 = 0 vs H1: P1 - p2 ≠ 0 B. H0: p1 - p2 > 0 vs H1- P1 - p2 < 0 C. H0: p1 - p2 > 0 vs H1: P1 - p2 ≠ 0 D. H0: p1 - p2 ≠ 0 vs H1: P1 - p2 = 0 E. None of the preceding

(Where p1 is the proportion of all high-income voters who supported a decrease in VAT; p2 is the same for the low-income voters). The hypotheses are:

 

A. H0: p1 - p2 = 0 vs H1: P1 - p2 ≠ 0

B. H0: p1 - p2 > 0 vs H1- P1 - p2 < 0

C. H0: p1 - p2 > 0 vs H1: P1 - p2 ≠ 0

D. H0: p1 - p2 ≠ 0 vs H1: P1 - p2 = 0

E. None of the preceding
