1. Researcher wants to test the association between alignment status and wire type. Here

variables alignment status and wire type are measured on nominal scale of measurement.
Alignment status is categorized as presence or absence. And wire type is categorized as A
or B. to test association between two variables measured on nominal scale of
measurement I use chi square test.
2. Application of chi square analysis here tells me if there is any significant association
between alignment status and wire type. This hypothesis test only tells about
independence of two variables and doesn’t give information about effect (odds ratio).
3. a) Research question is to know if alignment status and wire type are independent
variables.
b) Null hypothesis: there is no significant association between alignment status and wire
type. That is alignment status and wire type are independent.
c) Alternative hypothesis: there is significant association between alignment status...
