<h3>How to calculate the probability.</h3>

From the information given, it was stated that a polling agency is investigating the voter support for a ballot measure in an upcoming city election and that the the population proportion of voters who would support the ballot measure in region a is 0. 47.

Based on the complete information, the probability that the proportion of voters in the sample of region A that will support the ballot measure will be greater than 0.50 will be given as P(Z > 1.3441).

It should be noted that when this value is looked in the table, it will give a value of 0.0895.
