Answer:

The large sample n = 1713.96

Step-by-step explanation:

<u>Explanation</u>:-

given the population proportion was estimated to be 0.22

population proportion (P) = 0.22

The 95 % level of significance = 1.96≅ 2

The margin of  error = 0.02

The formula of margin error

                                   \frac{2\sqrt{p(1-p)} }{\sqrt{n} } = 0.02    …  ( i )

Substitute 'p' values in equation (1)

\frac{2\sqrt{0.22(1-0.22)} }{\sqrt{n} } = 0.02

cross multiplication and simplification, we get

2X0.414= 0.02 \sqrt{n}

\frac{2X0.414}{0.02} = \sqrt{n}

41.4 = \sqrt{n}

squaring on both sides, we get

the large sample n = 1713.96
