In a clinical trial, 15 out of 800 patients taking a prescription drug complained of flulike symptoms. Suppose that it is known that 2.9% of patients taking competing drugs complain of flulike symptoms. Is this sufficient evidence to conclude that less than 2.9% of this drug's users experience flulike symptoms as a side effect? (Let α=0.05)

2-Proportion Test

In a 2-proportion test, two separate proportions are measured at the same time, and their similarity is evaluated. It is also known as a 2-proportion z-test, and a comparison of two different proportions is done in this method.
