Hello,

I have never done statistical test so i am wondering if some one canhelp me find the 95% CI and pvalue of each variable i am comparing here.

Re: Confidence interval and p value

A p-value is based on a test, what test are you performing? What's your hypothesis?

I suspect since you have count data that a Chi Square or Fishers Test are more appropriate.

Hi Reeza,
Sorry I was not sure if it posted the first time I posted. My hypothesis id ALERT Group is from African American race, non- Hispanic ethnicity, Alert male have more male partners than any other group, Alert have more symptoms and had GCC in the past than other groups.
