Identify the population sample.
Population: ___ gym members
Sample: ___ gym members
Population: 124 gym members
Sample: 68 gym members
Total number of students included in the representative sample:
25 male students x 10 schools = 250 male students
25 female students x 10 schools = 250 female students
250 male students + 250 female students = 500 students
Therefore, 500 students were included in her representative sample.
To avoid bias in his study, Joe should choose randomly from each of the 50 states to make sure a representation of the entire country is included in the sample. This means he should choose an equal number of adults from each state.
10,000 adults / 50 states = 200 adults
Therefore, Joe should choose 200 adults from each of the 50 states for a total of 10,000 adults in the sample.
