Dear all,
I have a set of data with approximately 100 patiens treated for cancer in two groups in regards to increase in luteinising hormone. I have som problems understanding how the p-value can go below 0.05 when CI is 0.97 - 11.15.I know the p-value is sensitive to group size etc but I still cannot understand this result (pic below). Any ideas?
Best regards,
John Tapper
