Assume that the significance level is alpha equals 01 Use t

Assume that the significance level is alpha equals 0.1 . Use the given information to find the P-value and the critical value(s). The test statistic of zequals negative 1.17 is obtained when testing the claim that p less than 0.3 .

Solution

Zo =-1.17
Critical Value
The Value of |Z | at LOS 0.1% is 1.28
We got |Zo| =1.17 & | Z | =1.28
Make Decision
Hence Value of |Zo | < | Z | and Here we Do not Reject Ho
P-Value: Left Tail -Ha : ( P < -1.17 ) = 0.121
Hence Value of P0.1 < 0.121,Here We Do not Reject Ho
