Assume that the significance level is 005 Use the given info

Assume that the significance level is =0.05. Use the given information to find the P-value and the critical value(s). The test statistic of z=1.62 is obtained when testing the claim that p>0.7.

P-value equals =

The critical value(s) is/are =

)

Solution

Given : = 0.05 and z = 1.62

P-value for Right Tailed Test :

P(Z>1.62) = 1- P(Z<1.62)

                = 1 - 0.947

(In Z-table, find the row for 1.6 and the column for 0.02 Intersect the row and column and you find 0.947);

P(Z>1.62) = 0.0526

The Critical Value:

1- = 1- 0.05 = 0.95

Look up that value (.95) in the middle of the z-table. The area corresponds to a z-value of 1.645.This is Critical value for right tailed is 1.645.
