Testing of population proportion based on Z test
In some places in the US, people are aware of the need for
more care for older citizens, like Dr Hope In the election in one area, they
put forward a referendum that would increase the county sales tax by one cent
to pay for increased services for this important part of the community
Registered voters were asked to vote Yes, raise the tax to provide more
services to people 60 and older, or No, do not raise the tax to provide more
services to people 60+, on the referendum Fortunately, for the younger people
of the county who would pay most of the tax, it was defeated The discussion
that followed included a vigorous rehashing of the pro’s and con’s of the
referendum You accidentally were in attendance one night and had an idea: what
was the idea and how do you do it?
Hint: if there was a significant difference between those
voting Yes compared with the No’s, then If the Yes vote was 1001 and No
was 1258, do you have an argument?
