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

Solutions

Expert Solution

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
