3) in clinical trials of nasonex, 3774 adult and adolescent allergy patients (ages 12 and older) were randomly
divided into two groups. the patients in group 1 (control group) received the placebo, while the patients
in group 2 (experimental group) received 200 ug of nasonex. of the 1671 patients in the control group.
368 reported headaches as a side effect. of the 2103 patients in the experimental group, 494 reported
a side effect. at the 10% significance level, is there sufficient evidence to conclude that the
nicers that experienced headaches as a side effect is greater than the proportion of
proportion of nasonex users that experienced headaches as a side effect is pre
those in the control group?

Which scenarios are most effectively explored by conducting an experiment? there is more than one correct answer. select all that apply. researchers want to study the effectiveness of a particular drug for treating migraines. they want to know which dosage of the drug yields the best results with the least side effects. to ensure fair results, the researchers want to ensure that participants and dosage administrators do not know which dosage participants receive. a teacher wants to plan a class fieldtrip and quickly determine where students prefer to go for the class fieldtrip. a car mechanic wants to know which of two engine brands makes better-performing engines. he wants to test the engines in identical situations and rate their performance in a way that can be fairly measured. a chemist studies the properties of a metal compound. she wants to know how the sample size of the metal affects its ability to conduct electricity. she wants to conduct the research in a controlled environment to minimize bias. a realty company wants to know the average income of its clients. the company wants to gather data income from current clients.
