The manufacturer of Nexium claims that more than 94%% of patients taking the medication are healed within 3 weeks, In clinical trials, 213 of 224 patients suffering from acid reflux disease were healed after & weeks. Test the manufacture's claim at the ,01 level of significance. 7. A state that requires periodic emissions tests of cars operates two emission test stations - A and B - In one of its areas. Car owners have complained about a lack of uniformity of procedures at the two stations, resulting in different failure rates. A sample of 400 cars at Station A showed that 53 of those failed the test. A sample of 470 cars at Station B found that 51 of those failed the test. Testing at the 3% significance level, can it be concluded that the two population proportions for failure are different ?HYPOTHESIS TESTING TESTING TEMPLATE NAME Problem # 6 TYPE OF TEST : MEAN PROPORTION NUMBER OF POPULATIONS : ONE TWO SAMPLE SIZE : LARGE SMALL A NULL HYPOTHESIS Ha !
