Assume that the significance level is alpha = 0.01. Use the given information to find the P-value and the critical value(s). The test statistic of z = 1.91is obtained when testing the claim that p greater than 0.6.

P-value = _______

Solution

As we see, this is right tailed, as it says p is GREATER THAN 0.6.

Using a table/technology, the right tailed area of this is          
          
P(z >   1.91   ) =    0.028066607 [ANSWER, P VALUE]

****************************

Meanwhile, the critical z value, if the right tailed area is 0.01 (left tailed area 0.99) is, using table or technology,          
          
z =    2.326347874   [ANSWER, CRITICAL Z]
