two tailed test z= -2.47 what is p value

Question

Question

Answer 1

Answer #1

Answer :

given that :

Z = -2.47

now we need to find out the P value

two tailed test =

from the z normal distribution table, area to the left of z = -2.47 is

0.5 - 0.4932 = 0.0068 approximately.

hence ,

p- value = 2(0.0068)

= 0.136

P-value = 0.136
