For a test of H 0 p050 the z test statistic equals 081 FInd

For a test of H ₀: p=0.50, the z test statistic equals 0.81. FInd :

a) P value for H_a: p>0.50

b) P value for H_a: p 0.50

c) P value for H_a: p < 0.50

Solution

a)
P-Value: Right Tail - Ha : ( P > 0.81 ) = 0.20897
b)
P-Value: Two Tailed ( double the one tail ) - Ha : ( P != 0.81 ) = 0.41794
c)
P-Value: Left Tail -Ha : ( P < 0.81 ) = 0.79103
