Suppose you want to estimate the proportion of cars that are sport utility vehicles (SUVs) being driven in Kansas City, Missouri

ahrayia [7]

Answer:

The sample size 'n' = 721

Number of cars 'n' = 721

Step-by-step explanation:

Explanation:-

Given Population proportion 'p' = 0.40

Given Margin of error = 0.03

90% of level of significance

$Z_{\frac{\alpha }{2} } = 1.645$

The Margin of error is determined by

$M.E = \frac{Z_{\frac{\alpha }{2} S.D} }{\sqrt{n} }$

$0.03 = \frac{1.645 X \sqrt{0.40(1-0.40) } }{\sqrt{n} }$

on calculation , we get

0.03√n = 0.8058

$\sqrt{n} = \frac{0.8058}{0.03} = 26.86$

squaring on both sides , we get

n = 721.45≅721

conclusion:-

The sample size 'n' = 721

Number of cars 'n' = 721
