8.67 Free recall memory strategy. Psychologists who study
①memory often use a measure of "free recall" (e.g., the
RECALL number of correctly recalled items in a list of to-be-
remembered items). The strategy used to memorize the
list-for example, category clustering-is often just as
important. Researchers at Central Michigan University
developed an algorithm for computing measures of cat-
egory clustering in Advances in Cognitive Psychology
(Oct. 2012). One measure, called ratio of repetition, was
recorded for a sample of 8 participants in a memory study.
These ratios are listed in the table. Test the theory that the
average ratio of repetition for all participants in a similar
memory study differs from .5. Select an appropriate Type
I error rate for your test.

The radon levels-measured in becquerels per cubic meter (Bq/m³)-in the inner chambers of a sam- ple of 12 tombs are listed in the table. For the safety of the guards and visitors, the Egypt Tourism Authority (ETA) will temporarily close the tombs if the true mean level of radon exposure in the tombs rises to 6,000 Bq/m³. Consequently, the ETA wants to conduct a test to deter- mine if the true mean level of radon exposure in the tombs is less than 6,000 Bq/m³, using a Type I error probabil- ity of .10.
