Curing diabetes: Vertical banded gastroplasty is a surgical procedure that reduces the volume of the stomach in order to produce weight loss. In a recent study, 82 patients with Type 2 diabetes underwent this procedure, and 59 of them experienced a recovery from diabetes. Does this study provide convincing evidence that those with diabetes who undergo this surgery will recover from diabetes differs from 64%? Use the =α0.10 level of significance with the P-value method and Excel.
For the T-test of the single sample, does the GPA of a group of students who were considered gifted in primary school is higher than the university's mean GPA? How do you state your hypothesis and then how do you decide based on the t-test if we should reject the null hypothesis?
A local coach wants to see if training in light rooms or dark rooms impacts athlete performance. With the single team, the coach tries training in different conditions and takes measurements. She ran her analysis in Microsoft Excel and received the following output table. If the P value is less than 0.05, the null hypothesis may be rejected. Based on the data table, what decision should the coach make about the hypothesis? Coach should reject the null hypothesis. Coach should fail to reject the null hypothesis. Coach should accept the null hypothesis. Coach does not have enough information to decide.
An air conditioning unity company stockpiles air conditioning units in a large warehouse for shipment to retail stores. Sometimes in handling them the appliances get damaged. Even though the damage may be minor, the company must sell those units at drastically reduced prices. The company goal is to keep the level of damaged machines below 4%. One day an inspector randomly checks 53 air conditioning units and finds that 8 of them are damaged. Is this strong evidence that the warehouse is failing to meet the company goal? Test an appropriate hypothesis and state your conclusion. Be sure the appropriate assumptions and conditions are satisfied before you proceed. State the null and alternate hypothesis, and find the z-statistic and the p-value
Hypthesis testing In a 2011 National Institute on Alcohol Abuse and Alcoholism survey, 33% of American adults said that they had never consumed alcohol (USA TODAY, November 17, 2011). Suppose this result is true for the 2011 population of American adults. In a recent random sample of 2300 American adults, 35% said that they have never consumed alcohol. Using a 5% significance level, can you conclude that the current percentage of American adults who have never consumed alcohol is 33%?
A randomized double-blind clinical trial for a new drug has a null hypothesis of "There is no difference in the effect of the new drug as compared to a placebo." When the data results are analyzed, the researchers get a p-value of 0.07. What decision should the researchers make? A. We accept the null hypothesis that the drug is no better than a placebo. B. We cannot reject the null hypothesis that the drug is no better than a placebo. C. We accept the alternative hypothesis that the drug is no better than a placebo. D. We reject the alternative hypothesis that the drug is better than a placebo.
A marketing research firm wants to determine if a new advertising campaign has an effect on sales. The null hypothesis is that the campaign has no effect on sales, meaning the average sales before and after the campaign are equal. The firm conducts a two-sample t-test and obtains a t-statistic of 2.7 and a degrees of freedom of 20. What is the p-value of the hypothesis test?
