Question

You are conducting a study to see if the accuracy rate for fingerprint identification is significantly less than 63%. With Ha : p < 63% you obtain a test statistic of z = − 1.143 . Find the p-value accurate to 4 decimal places.

Answer 1

Answer:

p=0.1271

Step-by-step explanation:

Given : $H_a : p < 63\%$

            z = − 1.143

To Find :  Find the p-value accurate to 4 decimal places.

Solution:

We are given that You are conducting a study to see if the accuracy rate for fingerprint identification is significantly less than 63%.

$H_a : p < 63\%$

z = − 1.143

Refer the z table for p value

p=0.1271

Hence the p-value accurate to 4 decimal places is 0.1271
