Calculate P-value: P-value = (Keep four digits after decimal point)
iv) Choose All of the correct statements from the following:
Reject H, since p-value < a
Do not reject Ho since z is not in the rejection region
Do not reject Ho since p-value > a
Do not reject H, since p-value < «
Reject H, since z is in the rejection region
Reject H, since p-value > a
Expert Solution
Step 1
From the part i, the tail of the test is right tail test.
Test statistic=2.03
P value:
P=P(z>test statistic)
=P(z>2.03)
=1-P(z<2.03)
=0.0212, from the excel function, =1-NORM.DIST(2.03,0,1,TRUE)
