Answer #1

To determine the number of participants for having a reasonable and higher likelihood of the experiment supporting the research hypothesis if it is actually true in the larger population is to

c. determine the power before conducting the study.

Because, if the power is known before conducting the study then the researcher will be able to understand the likelihood of the trueness of the experiment about the intended population of interest.

a)A psychologist is planning a study on the effect of motivation on performance on an attention task. In this task, participants try to identify target letters in a stream of letters passing by at a rapid rate. The researcher knows from long experience that, under ordinary experimental conditions, the population of students who participate in this task identify a mean of 71 of the key letters, that the standard deviation is 10, and that the distribution is approximately normal. The...

1.Quit Smoking: The New England Journal of Medicine published the results of a 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. We conducted a hypothesis test to determine if the side effect rates are significantly different for nicotine patches versus bupropion at a 5% level of significance. (The normality conditions...

After reading an article about the benefits of acupuncture, a researcher decides to conduct an experiment to determine if acupuncture has an effect on back pain. The researcher recruits 11 people with chronic back pain to participate in a study. Each participant rates his or her back pain prior to the acupuncture and following the acupuncture. Ratings are made on a 10-point scale with higher numbers indicating greater back pain. For the study described above, how much of a difference...

After reading an article about the benefits of acupuncture, a researcher decides to conduct an experiment to determine if acupuncture has an effect on back pain. The researcher recruits 11 people with chronic back pain to participate in a study. Each participant rates his or her back pain prior to the acupuncture and following the acupuncture. Ratings are made on a 10-point scale with higher numbers indicating greater back pain. Test the researcher's assumption using an alpha level = .05,...

4. Previous research states, "no evidence currently exists supporting or refuting the use of electric fans during heat waves" in terms of mortality and illness. Counterintuitively, Public Health guidelines suggest not using fans during hot weather, with some research reporting the potential of fans accelerating body heating. You decide to research further this seemingly contradictory guidance, hypothesizing that the true population average core body temperature amidst higher ambient temperature and humidity levels while using an electric fan is greater than...
