text: ## Elementary Statistics (12th Edition)
  
  Range is the difference of the maximum and minimum of the set: range=36-0=36 years. Calculated by calculator, the mean is: 15.03 years. The variance is the sum of the differences of each value and the mean on the power of two, divided by the number of values minus 1: variance=$\frac{(10−15.03)^2+(29−15.03)^2+...+(23−15.03)^2}{33-1}=$94.5 years. The standard deviation is the square root of the variance: standard deviation=$\sqrt{94.5}=9.72$ minutes. By The Range Rule of Thumb the standard deviation is one fourth of the range:$\frac{36}{4}=9$ years. This estimated standard deviation is a little less than the real standard deviation, but very close to it.
explanation: The text extract appears to be from an elementary statistics textbook or a similar educational resource. It provides calculations for the range, mean, variance, and standard deviation of a dataset. The text also includes a comparison between the estimated standard deviation using the Range Rule of Thumb and the actual standard deviation. The extract does not contain a specific question but rather presents a series of statistical calculations and explanations.
distilabel_metadata.content: Evaluate the user given text extract and determine if it contains a math question and optionally and answer to this question.
  
  Output rules:
  
  1. Briefly describe the document and mention if it contains a question or a question and answer.
  2. Finalize the output with: Label: no-question,question,question-and-answer,multiple-question,multiple-question-and-answer
