Imagine that your professor is discussing the prevalence of psychological disorders in the general population, and he says, A study conducted in 2012 estimated that about 11 of the population has a psychological disorder at any one time.
If you were to estimate a confidence interval, based on this number11you would be most likely
a. to use the confirmation bias inappropriately.
b. to estimate this range by using the availability heuristic, which would be biased because of recent examples.
c. to rely too heavily on an anchor, and not make large enough adjustments to that anchor.
d. to use decision frames inappropriately.
Question 2Suppose that a student named John is asked to judge how many students are enrolled in his introductory biology class. He replies, about 100....well, maybe between about 90 and 110. Based on the discussion of confidence intervals, you predict that
a. John's estimate probably relies too heavily on the ease with which examples come to mind.
b. John is likely to be heavily influenced by the confirmation bias.
c. John probably relied too heavily on the initial anchor of 100 students.
d. John probably would have been wiser to use the representativeness heuristic to estimate the confidence intervals.
