Which of the following research scenarios uses a one sample t test design?Group of answer choices

a. Testing how much time of a 10 minute testing period mice will spend in one half of a divided cage. One half has cat scent present, the other no scent. If mice spend 5 minutes in each half, (without knowing the standard deviation), then there is no preference for either half.

b. Evaluate a memory-enhancing drug by measuring how many words one sample of people can recall after reading the list of words, without receiving the drug compared to a second sample that read the same words, and who received the drug.

c. Measure a training program’s effect on IQ scores (population mean and standard deviation are known) on a single sample of people who received the training.

d.
Quantify empathy levels in the elderly at age 80 and then again at age 85 for a single sample.
