A polling group surveyed a city in Scotland regarding residents' opinions on independence from the UK. The poll wants to find out whether there is strong evidence to show that a majority (> 50%) of the residents will vote 'Yes.' The survey polled 2000 residents, of which 1050 responded that they will vote 'Yes' on Scotland independence (52.5%). What are the null and alternative hypotheses?

Null: the percentage of 'Yes' votes is 52.5%; Alternative: the percentage of 'Yes' votes is greater than 52.5%

Null: the percentage of 'Yes' votes is greater than 52.5%; Alternative: the percentage of 'Yes' votes is 52.5%

Null: the percentage of 'Yes' votes is greater than 50%; Alternative: the percentage of 'Yes' votes is 50%

Null: the percentage of 'Yes' votes is 50%; Alternative: the percentage of 'Yes' votes is greater than 50%
