Question

A statistics professor claims that her lectures cause headaches in only 1% of those who listen to them. A disgruntled student believes that more than 1% of those who listen to the lecture actually get headaches.

Identify the population(s).
- All students who listen to the lecture.
- More than 1% of those who listen to the lecture actually get headaches.
- 1% of those who attend the class.
- the proportion of those who come to class compared to those who do get a headache.
What is the variable being examined for individuals in the population(s)?
- 1% of those who attend the lecture who get a headache.
- whether or not a student who listens to the lecture gets a headache.
- more than 1% of those who attend the lecture who get a headache.
- the proportion of those who listened to the lecture.
Is it categorical or quantitative?
- Categorical
- Quantitative
Identify the parameter(s).
- the proportion of those who listen to the lecture and develop a headache.
- the mean of those who listen to the lecture who get a headache.
- whether or not a person who listens to the lecture gets a headache.
- all individuals who come to class.
What is the claim?
- comparing two population means
- a population mean
- comparing two population proportions
- a population proportion
Which hypotheses do we want to test?
- H₀: p = 0.01
  H_a: p > 0.01
- H₀: p = 0.01
  H_a: p ≠ 0.01
- H₀: p ≠ 0.01
  H_a: p = 0.01
- H₀: p = 0.01
  H_a: p < 0.01
