Researchers are often interested in the likelihood of sampling outcomes. They may ask questions about the likelihood that a person with a particular characteristic will be selected to participate in a study. In this exercise, we will select a sample of one participant from the following hypothetical student population of men and women living on or off campus. The population is summarized in the following table.
| Male | Female | Row Totals | |
| On Campus | 30 | 25 | 55 |
| Off Campus | 20 | 25 | 45 |
| Column Totals | 20 | 50 | 100 |
1. What is the probability of selecting a male participant?
2. What is the probability of selecting a female participant?
3. What is the probability of selecting a student who lives on campus?
4. What is the probability of selecting a student who lives off campus?
5. What is the probability of selecting a male student, given that he lives off campus?
6. What is the probability of selecting a female student, given that she lives on campus?
7. What is the probability of selecting a male student, given that he lives on campus?
8. What is the probability of selecting a female student, given that she lives off campus?
9. What is the probability of selecting a student who lives on campus, given that he is a male?
10. What is the probability of selecting a student who lives off campus, given that he is a male?
11. What is the probability of selecting a student who lives on campus, given that she is a female?
12. What is the probability of selecting a student who lives off campus, given that she is a female?

Researchers in mental health fields are often interested in
evaluating the effectiveness of using food images to enhance
positive mood. Adapting a typical design from such studies, suppose
we have participants rate their mood change on a standard
self-report affect scale after viewing images of "comfort" foods,
fruits/vegetables (F/V), and random non-food images (used as a
control group). The results are given in the table at right for
this hypothetical study.

Researchers are often interested in the rate of political
participation based on neighborhood economic conditions. Create a
scatter plot of the variables and estimate the correlation between
these two variables (assume each is continuous).

Researchers may seem to be more often concerned with small
sample sizes and tests that, as a result, lack power, yet having a
very large sample can create its own set of problems. Speculate
these issues by pointing out the relationships between sample size
and power when the magnitude of effect is held constant. What other
implications can you gain from the information?

## Sampling distributions
Answer the questions in your own words but you may refer to
notes
1. What is a sampling distribution. Describe with an example
where the population is Fremont, CA and the parameter of interest
is whether the household owns a Tesla.
2. Describe the concept of sampling variability.
## Explain the Central Limit Theorem
Explain what the Central Limit Theorem tells you about the sampling
distribution. But don't use fancy technical terms. For example if
you were...
