Suppose that we are testing H₀: = ₀ versus H₁: < ₀. Calculate the P-value for the following observed values of the test statistic:
(a)z₀ = -2.18
(b)z₀ = -1.73
(c)z₀ = -2.50
(d)z₀ = -1.69
(e)z₀ = 0.57

Round your answers to five decimal places.

Solution

a)
Zo =-2.18
P-Value : Left Tail - Ha : ( P < -2.18 ) = 0.01463
b)
Zo = -1.73
P-Value : Left Tail - Ha : ( P < -1.73 ) = 0.04182
c)
Zo = -2.5
P-Value : Left Tail - Ha : ( P < -2.5 ) = 0.00621
d)
Zo =-1.69
P-Value : Left Tail - Ha : ( P < -1.69 ) = 0.04551
e)
Zo =0.57
P-Value : Left Tail - Ha : ( P < 0.57 ) = 0.71566
