H0: ð = 0.73vs. Ha: ð >0.73
H0: ð = 0.50vs. Ha: ð >0.50
H0: ð = 0.73vs. Ha: ð â 0.73
H0: ð = 0.50vs. Ha: ð â 0.50
H0: p =0.73vs. Ha: p >0.73
H0: p =0.50vs. Ha: p >0.50
H0: p =0.73vs. Ha: p â 0.73
H0: p =0.50vs. Ha: p â 0.50
H0: pĖ = 0.73vs. Ha: pĖ >0.73
H0: pĖ = 0.50vs. Ha: pĖ >0.50
H0: pĖ = 0.73vs. Ha: pĖ â 0.73
