a. Identify the population.
1. more than 5% of those who take the drug actually get headaches.
2. the proportion of those who take the drug who get a headache.
3. 5% of those who take the drug actually get headaches.
4. all responses of individuals who take the medication.
b. What is the variable being examined for individuals in the population(s)?
1. the proportion of those who take the drug who get a headache.
2. 5% of those who take the drug actually get headaches.
3. more than 5% of those who take the drug actually get headaches.
4. whether or not a person who takes the drug gets a headache.
Is it categorical orquantitative?
1. Quantitative
2. Categorical
c. Identify the parameter(s).
1. whether or not a person who takes the drug gets a headache.
2. the mean of those who take the drug who get a headache.
3. the proportion of those who take the drug who get a headache.
4. all individuals who take the medication.
d. What is the claim?
1. a population proportion
2. comparing two population means
3. comparing two population proportions
4. a population mean
e. Which hypotheses do we want to test?
1. H0: p = 0.05
Ha: p > 0.05
2. H0: p = 0.05
Ha: p < 0.05
3. H0: p = 0.05
Ha: p ≠ 0.05
4. H0: p ≠ 0.05
