During a clinical trial on seasonal allergy, a pharmaceutical company obtains the following data about the undesirable effects of the type of medication administered to patients. (a) What kind of chi-square test would be most appropriate to analyse these data – goodness of fit or homogeneity (independence)? Explain. (b) Using the appropriate chi-square tests with a 5% significance level, determine if the undesirable effects to patients is independent to the types of medication taken. i. Using the appropriate Minitab report....

Clinical trial The design of the clinical trial for this study represented a single centered, double blind, placebo-controlled trial that utilized randomization to target patients for the trial. The eligible patients for the study were aged 21-90 years and after receiving a biopsy, these patients had confirmed colorectal adenocarcinoma and were deemed eligible for receiving treatment for the surgery to remove their adenocarcinoma, but were instead given an opportunity to participate in this research trial with written informed consent. Potential...
