Use the given statement and find the P-value and critical value(s). The test statistic of z-1.84 is obtained when testing the claim that p- P-value= (Round to four decimal places as needed.)

Explanation / Answer

As we are testing the claim here that p = 0.5, therefore this is a two tailed test. The p-value here is computed from the standard normal tables as:

p = 2P(Z < -1.84 ) = 2*0.0329 = 0.0658

Therefore 0.0658 is the required p-value here.

Now as we are doing the two tailed test for 0.01 level of significance, we get from the standard normal tables as:

P( -2.576 < Z < 2.576 ) = 0.99

Therefore the critical values here are: -2.58, 2.58
