alex and allie want to conduct a survey on the use of exercise equipment at their gym. alex suggests surveying the first 20 members who enter the gym on monday. allie suggests surveying every 5th member who enters the gym during one week. which of the following best describes these suggestions? alexs suggestion is more likely to produce unbiased data than allies suggestion. allies suggestion is more likely to produce unbiased data than alexs suggestion. both alex and allie suggest a method that is equally likely to produce unbiased data. neither alex nor allie suggests a method that is likely to produce unbiased data.
Answer
# Brief Explanations:
Alex's method of surveying the first 20 members on Monday is a convenience - sample and may only represent early - morning or Monday - specific gym - goers. Allie's method of surveying every 5th member over a week is a systematic sample but still may have biases as it depends on the time of day and day of the week when members enter. Overall, both methods are likely to have biases.
# Answer:
Neither Alex nor Allie suggests a method that is likely to produce unbiased data.
