Question 143220: Do a larger proportion of people own cats live in houses or apts?
Group 1 Houses Group 2 Apts
Number who own cats: x1= 833 x2 = 692
Number Surveyed: n1 = 850 n2 = 740
I need to perform the five step hypothesis test. Answer by stanbon(75887) (Show Source):
You can put this solution on YOUR website! Do a larger proportion of people own cats live in houses or apts?
Group 1 Houses Group 2 Apts
Number who own cats: x1= 833 x2 = 692
Number Surveyed: n1 = 850 n2 = 740
I need to perform the five step hypothesis test.
---------------
Ho: p(house)-P(apts) = 0
Ha: p(house)-p(apts > 0
-----------------------------
phat(house) = 83/850 = 0.98
phat(apts) = 692/740 = 0.935...
----------
Critical value = 1.645
-----------
Using a TI-83 2-PropZTest I get the following:
test statistic: 4.50649
p-value: 0.0000032984...
-------------
Conclusion: Since p-value is less than alpha =5%, reject Ho.
The proportion of cats in houses is greater than the proportion of cats in apts.
