Question

Assume that the significance level is a=0.1. Use the given information to find the P-value and the critical value(s). The test statistic of z = 1.57 is obtained when testing the claim that p>0.3. Click here to view page 1 of the Normal table. Click here to view page 2 of the Normal table. P-value (Round to four decimal places as needed.)

Answer 1

solution:

Test statistic = z=1.57

P(z >1.57 ) = 1 - P(z < 1.57 ) = 1-0.9418=0.0582

P-value = 0.0582

$\alpha$= 0.1

CRITICAL VALUE = Z $\alpha$ = Z0.1 =1.282
