The value is 
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

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

=>
=>
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


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

So
