What is hypothesis testing?

Selecciona una de las siguientes respuestas posibles:

  • How likely a particular value or set of values is in the given data

What is the sampling distribution?

Selecciona una de las siguientes respuestas posibles:

  • A hypothetical distribution of values of a particular population parameter made by repeatedly sampling "n" times from a sample and calculating the value of the statistic for each sample

  • A hypothetical distribution of values of a particular sample statistic made by repeatedly sampling "n" times from a population and calculating the value of the statistic for each sample
