Question

The Government of Jamaica want to implement a new tax per babies born, i.e. the more
children you have the more tax you pay. They conducted a survey in the two major cities;
Kingston and Montego to determine the level of support from the people. A random sample
of 220 people was chosen from Kingston, 160 supported the claim and 30 were opposed,
the others were neutral. A random sample of 170 people was chosen from Montego Bay, 90
supported and the tax, 40 did not and the others were neutral.
Find the probability that the support in Kingston is 8% less than the support in Montego Bay.

Answer 1

b. Construct a 90% confidence interval to estimate the difference in proportion
(percentage) of residence from these two cities that support this proposal.
c.Test the hypothesis at the 95% level of significance that the support for the tax in
Montego Bay is 6% more than the support in Kingston.
d. Test the hypothesis at the 95% level of significance that there was no difference in
the sample proportions that do not support the claim in both cities
