A polling agency is investigating the voter support for a ballot measure in an upcoming city election. The agency will select a

Setler79 [48]

Answer:

The value is $P( X > 0.50) = 0.089264$

Step-by-step explanation:

From the question we are told that

The sample size is n = 500

The population proportion is p = 0.47

Generally given that the sample size is sufficiently large , the mean of this sampling distribution is mathematically represented as

$\mu_x = p = 0.47$

Generally the standard deviation of the sampling distribution is mathematically represented as

$\sigma = \sqrt{\frac{p(1- p )}{ n} }$

=> $\sigma = \sqrt{\frac{ 0.47 (1-0.47 )}{ 500 } }$

=> $\sigma = 0.0223$

Gnerally the probability that the proportion of voters in the sample of Region A who support the ballot measure is greater than 0.50 is mathematically represented as

$P( X > 0.50) = P( \frac{ X - \mu }{ \sigma } > \frac{ 0.50 - 0.47 }{ 0.0223 } )$

$\frac{X -\mu}{\sigma } = Z (The \ standardized \ value\ of \ X )$

=> $P( X > 0.50) = P( Z> 1.3453 )$

From the z table the area under the normal curve to the left corresponding to 1.3453 is

$P( Z> 1.3453 ) = 0.089264$

So

$P( X > 0.50) = 0.089264$
