Answer:
The calculated value Z = 3.775 > 1.96 at 0.05 level of significance
Null hypothesis is rejected
The Two Population proportion are not equal
<u>Step-by-step explanation</u>:
<em>Given first sample size n₁ = 677</em>
<em>First sample proportion </em>
<em> </em><em></em>
Given second sample size n₂ = 3377
<em>second sample proportion </em>
<em> </em><em></em>
<u><em>Null Hypothesis : H₀ :</em></u><em> p₁ = p₂.</em>
<u><em>Alternative Hypothesis : H₁</em></u><em> : p₁ ≠ p₂.</em>
Test statistic
where
P = 0.2036
Q = 1 - P = 1 - 0.2036 = 0.7964
Z = 3.775
<em>Critical value ∝=0.05</em>
<em>Z- value = 1.96</em>
<em>The calculated value Z = 3.775 > 1.96 at 0.05 level of significance</em>
<em>Null hypothesis is rejected </em>
<em>The Two Population proportion are not equal</em>
