In: Statistics and Probability
In order to test HO: p = 0.59 versus H1: p < 0.59, use n = 150 and x = 78 as your sample proportion.
Using your TI 83/84 calculator device, find the P-value with the appropriate Hypothesis Test
Use a critical level α = 0.01 and decide to Accept or Reject HO with the valid reason for the decision.
A. My P-value greater than α Alpha, so I Reject Null Hypothesis
B. My P-value greater than α Alpha, so I Accept Null Hypothesis
C. My P-value less than α Alpha, so I Accept Null Hypothesis
D. My P-value less than α Alpha, so I Reject Null Hypothesis
We have given hypothesis as
n = 150
x = 78
Path for Ti -83 and Ti -84 calculator
Press " STAT " key
Select " TESTS "
Select " 1 - PropZtest " Press " Enter "key
p0 = 0.59 ( Value of p for null hypothesis H0)
x = 78
n = 150
Prop : < p0 (We select < p0 beacuse our H1 has < sign )
Select " Calculate " press " enter "
Z = Test statistics = -1.743113777
p = p value = 0.0406568295
we have given α = 0.01
Decision rule
H0: Notation for the null hypothesis
p-value = 0.0406568295 and α = 0.01
0.0406568295 > 0.01 We do not reject H0
We are not rejecting H0 That means we accept H0
We are not rejecting Nulll hypothesis That means we accept Nulll hypothesis
The correct choice is (B)
My P-value greater than α Alpha, so I Accept the Null Hypothesis
Final answer:-
p = p-value = 0.0406568295
The correct choice is (B)
My P-value greater than α Alpha, so I Accept Null Hypothesis
