A new drug, Zia, is being tested for lowering blood pressure. The company claims that less than 10% of users experience side effects. In a clinical trial of 650 randomly selected patients who received Zia, 52 reported side effects. Is there evidence at the ∝= 0.05 significance level to support the company’s claim?

a) State the null and alternative hypothesis

b) Calculate the test statistic (by hand!) (2 decimal places)

c) Reject or Fail to reject the null hypothesis? Why? (you must reference a p-value)

d) Write your conclusion

In a clinical trial, 25 out of 881 patients taking a prescription drug complained of flulike symptoms. Suppose that it is know that 2.6% of patients taking competing drugs complain of flulike symptoms. Is there sufficient evidence to conclude that more than 2.6% of this drug's users experience flulike symptoms as a side effect at the (alpha) a=0.1 level of significance? 1) What are the null and alternative hypotheses? 2) What is the test statistic? 3) What is the P-value?...

When subjects were treated with a​ drug, their systolic blood pressure readings​ (in mm​ Hg) were measured before and after the drug was taken. Results are given in the table below. Assume that the paired sample data is a simple random sample and that the differences have a distribution that is approximately normal. Using a 0.05 significance​ level, is there sufficient evidence to support the claim that the drug is effective in lowering systolic blood​ pressure? Before 161 169 158...

Identify the null and alternative hypothesis(in symbolic and sentence form), test statistic, P-value(or critical values), conclusion about the null hypothesis, and final conclusion that addresses the original claim (Don’t just say Reject the null hypothesis or fail to reject the null hypothesis). 1. In a clinical study of an allergy drug, 108 of the 202 subjects reported experiencing significant relief from their symptoms. At the 0.01 significance level, test the claim that more than half of all those using the...
