Jillian Archer 1.) Stents vs. Surgery a.) State the null and alternative hypotheses and indicate where the claim is . Circle or highlight the correct sign and fill in the value in the null and the alternative hypothesis. 0 : H p    p = .386 : a H < p   ___ P _=/ .386 b.) Perform the test by finding the p-value (use your calculator, 1-PropZTest or StatCrunch). p-value= .015 c.) Make the appropriate decision to reject or fail to reject , indicate why you made this decision. Fail to reject, P value greater than .01 d.) State the conclusion about the claim for this hypothesis test. There is not enough evidence at the 0.1 level of significance to reject the null hypothesis at .386 2.) Drug-eluting vs. Bare Metal Stents a.) State the null and alternative hypotheses and indicate where the claim is . Circle or highlight the correct sign and fill in the value in the null and the alternative hypothesis. 0 : H p    P > or equal to .119 : a H < p   p < .119

b.) Perform the test by finding the p-value (use your calculator, 1-PropZTest or StatCrunch). p-value= 0 c.) Make the appropriate decision to reject or fail to reject , indicate why you made this decision. Reject null hypothesis because p value is less than level of significance. d.) State the conclusion about the claim for this hypothesis test. There is not enough evidence at the .01 significance level to sample data to support the proportion of patients who had setbacks. 3.) Stents vs. Medicine a.) State the null and alternative hypotheses and indicate where the claim is . Circle or highlight the correct sign and fill in the value in the null and alternative hypotheses. 0 : H p    p < or equal to .156 : a H < p   p > .156 b.) Perform the test by finding the p-value (use your calculator, 1-PropZTest or StatCrunch ). p-value= .065 c.) Make the appropriate decision to reject or fail to reject , indicate why you made this decision. Fail to reject the null P value greater than level of significance d.) State the conclusion about the claim for this hypothesis test. Fail to reject the null There is not sufficient evidence at the .01 level of significance to conclude that the proportion was worse at .156 from only medicine.
