Question

Use the given data to find the minimum sample size required to estimate a population proportion or percentage.

Margin of error: five percentage points; confidence level 95%; from a prior study, Modifying Above p with caret is estimated by the decimal equivalent of 58%

Answer #1

Solution :

Given that,

=58% = 0.58

1 - = 1 - 0.58= 0.42

margin of error = E = 5% = 0.05

At 95% confidence level the z is ,

= 1 - 95% = 1 - 0.95 = 0.05

/ 2 = 0.05 / 2 = 0.025

Z_{/2}
= Z_{0.025} = 1.96 ( Using z table ( see the 0.025 value in
standard normal (z) table corresponding z value is 1.96 )

Sample size = n = (Z_{/2}
/ E)^{2} *
* (1 -
)

= (1.96 / 0.05)^{2} * 0.58 * 0.42

= 374.32

Sample size = 374
