Explanation / Answer

Ho: __________________________p=0.74_____________________________________ Ha:____________________________p not equal0.74___________________________________ Rejection Criteria: ____Z<-1.96 orZ>1.96____________________________ Test Statistic:__
Z=(p_hat - p)/ sqrt(p*(1-p)/n)
=(0.55-0.74)/sqrt(0.74*(1-0.74)/260)=__-6.98______________________ Decision:____Since Z=-6.98 <-1.96, rejectHo._______________________ Conclusion:____the report is notcorrect.___________________________ Rejection Criteria: ____Z<-1.96 orZ>1.96____________________________ Test Statistic:__
