Question

In a clinical​ trial, 23 out of 898 patients taking a prescription drug daily complained of flulike symptoms. Suppose that it is known that 2.3​% of patients taking competing drugs complain of flulike symptoms. Is there sufficient evidence to conclude that more than 2.3​% of this​ drug's users experience flulike symptoms as a side effect at the alpha equals 0.05 level of​ significance? Because np 0 left parenthesis 1 minus p 0 right parenthesisequals 18 greater than ​10, the sample size is less than ​5% of the population​ size, and the sample can be reasonably assumed to be random, the requirements for testing the hypothesis are satisfied. ​(Round to one decimal place as​ needed.)
