SAT Inference, Margin, and Model Claims

This skill tests what a sample can support: margin of error, confidence, and whether a study allows a causal claim. A sample percentage is an estimate with a range around it, not an exact value for the population.

In a random sample for the classroom shaded mirror sorting roster, 53% of respondents supported a proposal about recycled glass tiles from the indoor set. The margin of error is 4 percentage points. Which interval is best supported for the population support?

  1. A53% to 57%
  2. B45% to 61%
  3. C49% to 57%correct
  4. D57% to 61%
Why C is correct — and why the others are not

A margin of error of 4 points around 53% gives 49% to 57%. That reasoning is tied to the item-specific detail about Inference, margin, and model claims. A final check is matching the final number to the quantity described in words.

A. This value results from treating the sample percent as exact or doubling the stated margin of error

B. This value results from treating the sample percent as exact or doubling the stated margin of error

D. This value results from treating the sample percent as exact or doubling the stated margin of error

In a random sample for the bookmobile open podium lighting route card, 54% of respondents supported a proposal about clinic reminders from the evening group. The margin of error is 5 percentage points. Which interval is best supported for the population support?

  3. C59% to 64%
  4. D49% to 59%correct
Why D is correct — and why the others are not

A margin of error of 5 points around 54% gives 49% to 59%. This matches the evidence or condition involving Inference, margin, and model claims. A final check is checking that both equations or conditions are satisfied.

A. This value results from treating the sample percent as exact or doubling the stated margin of error

B. This value results from treating the sample percent as exact or doubling the stated margin of error

C. This value results from treating the sample percent as exact or doubling the stated margin of error

In a random sample for the workshop daily sensor sampling floor plan, 56% of respondents supported a proposal about serialized novels from the lower-price group. The margin of error is 3 percentage points. Which interval is best supported for the population support?

  1. A56% to 59%
  2. B53% to 59%correct
  3. C50% to 62%
  4. D59% to 62%
Why B is correct — and why the others are not

A margin of error of 3 points around 56% gives 53% to 59%. The key support is the way the item treats Inference, margin, and model claims. A final check is using the equation form named in the stem.

A. This value results from treating the sample percent as exact or doubling the stated margin of error

C. This value results from treating the sample percent as exact or doubling the stated margin of error

D. This value results from treating the sample percent as exact or doubling the stated margin of error

FAQ

Inference, Margin, and Model Claims questions

What does margin of error tell me?

The range around the sample estimate in which the true population value plausibly lies. Wider margins mean less precision.

When can a study support cause and effect?

Only with random assignment to groups. A survey or observational study supports association, not causation.
