Question
Chapter 7, Problem 7.1AYK
To determine
To identify: the individuals, response variable and treatments of a given experiment.
Expert Solution & Answer
Answer to Problem 7.1AYK
The individuals are healthy people aged 18-40 who either take placebo pills or extract of Ginkgo leaves and participate in the experiment.
The two treatments are administration of i) placebo pills and ii) extract of Ginkgo leaves
Response variable is number of missed letters “e” which do not have X mark on it.
Explanation of Solution
A study assigns healthy people aged 18-40 to take either Ginkgo extract or placebo pills. After lunch, they are asked to read 7 pages of random letters and place an X over every e. Number of misses are counted. This experiment is carried to know whether extract of Ginkgo leaves effects the post lunch dip.
