Chapter B.4, Problem 5AYU

Voice-Recognition Systems Have you ever been frustrated by computer telephone systems that do not understand your voice commands? Quite a bit of effort goes into designing these systems to minimize voice-recognition errors. Researchers at the Oregon Graduate Institute of Science and Technology developed a new method of voice recognition (called a remapped network) that was thought to be an improvement over an existing neural network. The data shown in the next column are based on results of their research. Does the evidence suggest that the remapped network has a different proportion of errors than the neural network? Use the α = 0.05 level of significance.

"Coffee drinkers often claim that the caffeine in the coffee makes them more alert. A researcher wonders if this enhanced alertness is merely an illusion or if caffeine actually makes people more alert. To test the effect of caffeine on alertness, the researcher asks people to drink one cup of caffeinated coffee, one cup of plain water, one cup of caffeinated water, or one cup of decaffeinated coffee. After drinking the beverage each participant was given an electroencephalogram (EEG). The researcher hypothesized that the caffeinated beverages would result in greater electrical activity than the non-caffeinated beverages. Which of the following would be most likely to increase the size of the treatment effect in this study? "     Only use people in the study who are between the ages of 25 and 35 rather than 25 and 75.     Increase the amount of beverage participants drink from one cup to two cups.     Have experienced EEG technicians collect data rather than train students…
