![There is some concem that if women over age 59 who take supplemental hormones also drink alcohol, their hormone levels will rise too high. Seventeen volunteers on hormone therapy were randomly divided into two groups, as were 18 other volunteers not on hormone
therapy In each case, one group drank an alcoholic beverage, the other a nonalcoholic beverage. An hour later everyone's hormone level was checked. Only those on supplemental hormones who drank alcohol showed a marked increase
This experiment used treatments. (Type a whole number.)
e) Identify the response variable measured.
The response variable is
) Identify the design (completely randomized, blocked, or matched).
This experiment has a
7 design.
9) Identify whether the experiment was blind (or double-blind).
O A. This experiment is single-blind. The subjects were blinded.
O B. This experiment is double-blind.
O C. This experiment is single-blind. The evaluators were blinded.
O D. It is not known whether any blinding occurred.
h) Identify the nature and scope of the conclusion regarding what the results of the experiment may or may not indicate.
O A. This experiment indicates that drinking alcohol leads to increased hormone levels among those taking hormone supplements
O B. The experiment indicates that women over 59 who take hormone supplements should not drink alcohol.
OC. This experiment indicates that taking hormone supplements leads to increased hormone levels among those drinking alcohol.
O D. This experiment indicates that drinking alcohol leads to dangerous hormone levels among those taking hormone supplements.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F216c0e67-e7b4-4d7b-9b6b-a6ff16384909%2Fbfa2868d-ce89-4f0f-a0a4-9bf41ee51845%2F7jjm1k_processed.jpeg&w=3840&q=75)
