When I'm using my ti-84 for every other problem, I'm golden. This one particular question, is not being calculated correctly. P1

This is what I have:

Ho: P1 = P2; H1: P1 < P2

Test Statistic: Calculated by entering: Stat-Tests-6:2propzTest (i'm getting a z-score that is completely off)

my calculated z-test stat: -1.37; the books answer: -1.23

My calculated P-Value: .0859; the books answer: .112
