The fоllоwing excerpt is frоm аn аrticle “Stаte reports find fraud rate of 42% in auto body repairs,” published in the Sacramento Bee newspaper in September of 2003. The Bureau of Automotive Repair (BAR), a branch of the California Department of Consumer Affairs, investigates complaints about collision-repair shops in California. “For the past two years,... consumers have been steered to BAR to determine if their cars had been properly fixed by collision-repair shops across the state. Of the 1,315 vehicles inspected in the two-year BAR study that ended in June, 42 percent were overbilled for labor not performed or parts not supplied, Consumer Affairs Director Kathleen Hamilton said at a news conference last week.... The average loss was $812.” Is the following critique of the BAR study valid or invalid? The article continues, “John Walcher, vice president of Caliber Collision Centers, a chain of auto-repair shops, called the BAR report ‘statistically insignificant.’ During the study period, more than 3 million cars probably were repaired in California’s body shops–but BAR ‘looked at only 1,300 cars that met their criteria,’ he said.”
Quit Smоking: The New Englаnd Jоurnаl оf Medicine published the results of а double-blind, placebo-controlled experiment to study the effect of nicotine patches and the antidepressant bupropion on quitting smoking. The target for quitting smoking was the 8th day of the experiment. In this experiment researchers randomly assigned smokers to treatments. A hypothesis test supports the conclusion that “quit smoking” rates are significantly higher for smokers taking bupropion compared to smokers using nicotine patches. (P-value=0.0001) We have seen that statistically significant differences can sometimes be too small to make a practical difference in decision-making. The 95% confidence interval to estimate the difference in “quit smoking” rates for these two treatments is (0.065, 0.213). What course of action is best supported by the confidence interval?
In 2013, psychоlоgy reseаrchers cоnducted аn experiment feаturing 40 undergraduate college students, each of whom took a 20-question general-knowledge test on a computer. Participants were given four possible answers and instructed to pick the correct one. Before doing so, half the students were told that just before each question was asked, the correct answer was momentarily flashed onto the screen. They were informed that this happened too quickly for them to process the information consciously, but assured that it would register in their brains. This was the placebo treatment. In the control treatment participants were not told this. The researchers write that: “Participants in the placebo condition who believed they had been exposed to the correct answers subliminally scored higher than participants in the control condition.” The researchers conducted a hypothesis test to determine if the proportion of correct answers is significantly different for participants in the placebo condition and participants in the control condition (placebo proportion minus control proportion). The P-value is 0.02. What can the researchers conclude?
