Question

If you use a 0.05 level of significance in a​ two-tail hypothesis​ test, what decision will you make if Z STAT= -/+1.86?

Answer 1

solution:

Test statistic = z =1.86

P(z > 1.86) = 1 - P(z < 1.86) = 1-0.9686=0.0314 using z table

P-value = 2*0.0314=0.0628

= 0.05

P-value >

do not Reject the null hypothesis .

P(z < -1.86) =0.0314 using z table

P-value = 2*0.0314=0.0628

= 0.05

P-value >

do not Reject the null hypothesis .
