The placebo effect is particularly strong in patients with Parkinson's disease. To understand the workings of the placebo effect, scientists measure activity at a key point in the brain when patients receive a placebo that they think is an active drug and also when no treatment is given. The same six patients are measured both with and without the placebo, at different times.The six differences (treatment minus control) had x = −0.331 and s = 0.172. Is there significant evidence of a difference between treatment and control? (Round your answer to two decimal places. Assume a 95% confidence level.)

Two types of medical devices used for knee replacement are being studied to see if the type of knee replacement used affects the rate of infection for a specific bacterial infection. The infection rate for a specific bacterial infection after surgery for device A is 0.0043. The rate for the same bacterial infection is 0.0121 for device B. How does the risk of developing the bacterial infection in individuals using device B compare to the risk of developing the bacterial infection in individuals using device A?
By accident, Janae has been making decaffeinated coffee for her co-workers for the entire week. But some of her co-workers have claimed that the extra boost of caffeine has helped them focus on their work.What does the placebo effect mean in this specific situation? a.) The benefit is the result of the "control" (coffee, although decaffeinated) and not an effect of the "active ingredient" (caffeine). b.) The benefit is the result of the fact that the "treatment" (coffee, although decaffeinated) contains another "active ingredient" besides caffeine. c.) The benefit is due to the fact that the co-workers are given a "treatment" (coffee, although decaffeinated) and not an effect of the "active ingredient" (caffeine). d.) The co-workers get a benefit from the "treatment" (coffee, although decaffeinated) since they also drink coffee at the coffee shop across the street during breaks.
Your math teacher Ms. Washington notices that students with calculators do better on her math tests than those without calculators. To test her hypothesis, she randomly chooses 20 students and tracks their progress. She then gives 10 of those students a calculator and after a period of times compares progress again. The calculator group showed an increase. Which fact would lead you to believe that the relationship between calculator and progress may be one of causation? Tim’s scores decreased with the calculator. Tom’s scores increased with the calculator. A control group was used and the subjects were chosen randomly. Tammy’s scores did not change with the calculator.
In Dr. Potter’s study of ‘Objective Increases in Fear Based on Type of Haunting’, he reported that ghosts earned a z-score of 0.93, spirits earned a z-score of -0.75, and phantoms earned a z-score of -1.18. Assuming that a z-score of 0.00 represents the average amount of fear a person experiences during a haunting, answer the following questions: Which of the hauntings tested would you select if you wanted to increase fear as much as possible? Why would you choose this haunting? Which of the hauntings would you give to someone if you wanted to decrease fear as much as possible? Why would you choose this haunting?
Ten years ago, the town of Easton decided to increase its annual spending on education so that its high school graduates would be able to earn higher wages. Now Easton has asked you to evaluate the effectiveness of the spending increase. Their data show that before the spending increase, the average annual salary of recent high school graduates was $25,000 and that now that average salary has risen to $28,500. Fortunately for your analysis, a neighboring community (Allentown) did not change its annual spending on education. Ten years ago, recent Allentown high school graduates earned an average of $22,500, and now that average is $23,750. (b) What underlying assumption do you have to make in order for your estimate to be valid? What might cause your underlying assumption to be invalid?

One effect of the pesticide DDT upon birds is to inhibit the production of the enzyme carbonic anhydrase, which controls calcium metabolism. It is believed that this causes eggshells to be thinner and weaker than normal and makes the eggs more prone to breakage. An experiment was conducted where 16 sparrow hawks were fed a mixture of 3 ppm dieldrin and 15 ppm DDT (a combination often found in contaminated prey). The first egg laid by each bird was measured, and the mean shell thickness was found to be 0.19 mm. A “normal” eggshell has a mean thickness of 0.2 mm. What are the null and alternative hypotheses?

In a recent survey, ice cream truck drivers in Cincinnati, Ohio, reported they make about $280 in income on a typical summer day. The income was generally higher on days with longer work hours, particularly hot day, and on holidays. The IceCream data file includes five weeks of the driver's daily income (Income), number of hours on the road (Hours), whether it was a particularly hot day (Hot = 1 if the high temperature was above 85-degrees F, 0 otherwise), and whether it was a Holiday (Holiday = 1, 0 otherwise). 1. Predict the income of a driver working 8 hours on a hot holiday. (Round to the nearest dollar.) 2. Predict the income of a driver working 8 hours on a hot day if it was not a holiday. (Round to the nearest dollar.)
