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
