How to find margin of error & confidence interval on TI-83 in this problem?
Assume you plan to construct a 95% confidence interval.
Number of applications in sample:
In 2003: 42 Current Year: 33
Number of online applications in sample:
In 2003: 14 Current Year: 18
I'm thinking it's supposed to be set up like an n1, x1, n2, x2 type problem but when I used the 2PropZtest it didn't give the margin of error.
Would anyone happen to know how to calculate the margin of error and the 95% confidence interval? I know the answers because of my class's walkthrough, but it doesn't describe how to arrive at the answers on a calculator, it just says "use technology."
Any help is appreciated, thanks!!
