Question

1.11 buteyko method, scope of inference: exercise 1.4 introduces a study on using the buteyko shallow breathing technique to reduce asthma symptoms and improve quality of life. as part of this study 600 asthma patients aged 18 - 69 who relied on medication for asthma treatment were recruited and randomly assigned to two groups: one practiced the buteyko method and the other did not. those in the buteyko group experienced, on average, a significant reduction in asthma symptoms and an improvement in quality of life.
a) identify the population of interest in the study.
o the researchers
o the 600 asthma patients aged 18 - 69 who rely on medication for asthma treatment
o all asthma patients aged 18 - 69 who rely on medication for asthma treatment
o all asthma patients aged 18 - 69 who rely on medication for asthma treatment
o all asthma patients from all ages who rely on medication for asthma treatment
b) identify the sample in this study.
o all asthma patients from all ages who rely on medication for asthma treatment
o all asthma patients aged 18 - 69 who rely on medication for asthma treatment
o the researchers
o the 600 asthma patients aged 18 - 69 who rely on medication for asthma treatment
c) can the results of the study can be generalized to the population?

Explanation:

a) The population of interest is the entire group that the study aims to draw conclusions about. Here, the study is about asthma - patients aged 18 - 69 who rely on medication for asthma treatment.
b) The sample is the subset of the population that is actually studied. In this case, it's the 600 recruited asthma patients aged 18 - 69 who rely on medication for asthma treatment.

Answer:

a) all asthma patients aged 18 - 69 who rely on medication for asthma treatment
b) the 600 asthma patients aged 18 - 69 who rely on medication for asthma treatment
