Question

Part a) Find H0 and H1, find the p-value using technology, and decide if you reject or do not reject the null hypothesis. In a clinical trial 35 out of 950 patients taking a prescription drg complained of ulike symptoms. Suppose that it is known that 26% of patients taking competing drugs complain of flulike symptoms. Is there sufficient evidence to conclude that more than 2.6% of this dru s users experience ke symptoms as a side afect at he ?-0.1 level of significance? Ho: p L versus H1:p = > Part b) Y/N Use technology to find the p-value, and Reject or do no reject null hypothesis because the p-value is greater or smaller? Test the hypothesis using the P-value approach. Be sure to verify the requirements of the test. Ho: P 0.49 versus H1: p 0.49 n 150, x-66, ?-0.05 Is npo (1 Po O Yes O No

Explanation / Answer

Solution

(a) H0 : p = 0.026

H1 : p > 0.026

(b) p0 = 35/950 = 0.0368

950*0.026*(1-0.026) = 24.06> 10

z = (35 -24.7)/(24.06)0.5 = 2.1

p value = 0.018, p value is smaller

reject the null hypothesis
