(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Suppose that we are testing H_0: [tex]\mu[/tex] =[tex]\mu_0[/tex] versus H_1: [tex]\mu[/tex] [tex]\neq[/tex][tex]\mu_0[/tex]. Calculate the P-value for the following observed values of the test statistic.

a: z_0 =2.45

e: z_0=-0.25

2. Relevant equations

none

3. The attempt at a solution

I got part a by using the equation, P=2[1-[tex]\Phi[/tex](z_0)]. I got the value for the probability from the table in the book since it's a normal distribution and the p-value was equal to .014286.

Then for part e, I tried using the same equation as before, but I got a p-value of 1.19. My equation was P=2[1-.401294]

Can someone help with what I'm doing wrong? Thanks in advance
