Answer:
The sample size 'n' = 384
Step-by-step explanation:
<u>Step(i)</u>:-
Given data the margin of error = 0.05
The margin of error of the estimation of a population proportion is determined by
<u><em>Step(ii)</em></u>:-
In data not given sample proportion 'p' but
we know that
cross multiplication, we get
0.05 ×√n = 0.98
<em>squaring on both sides, we get</em>
<em>n = 384.16≅ 384</em>
<u><em>Final answer</em></u><em>:-</em>
<em>The sample size 'n' = 384</em>
