Hello: Can anybody explain this for me please?
question:
I have 2 columns with vacation rentals yes or no for 2 columns Fall 2010 Fall 2012
Fall 2010 - proportion of units rented = 70/200 = 0.35
Fall 2012 - proportion of units rented = 70/150= 0.467
questions:
Find 95% confidence interval for difference in proportions? (fall 2012 - fall 2010)
Will Fall 2012 have higher rentals than Fall 2010?
null hyp - Fall 2012 <= Fall 2010 rentals
alt hyp - Fall 2012 rentals > Fall 2010 rentals
Can you tell me how i can do this in stat tools or excel and the answer please?
