Drawing Conclusions from Samples

IN THIS PART …

  • Use confidence intervals to provide a range of possible values for a population parameter; these can be constructed for any population parameter: mean, variance, standard deviation, and so on.
  • Discover the techniques that are used to estimate confidence intervals for the population mean, including the standard normal distribution and the Student’s t-distribution.
  • Draw conclusions about population properties — from a single population variance to multiple population variances — with hypothesis testing.
  • Use the chi-square distribution to test whether a population conforms to a specific probability distribution — a goodness of fit test.
  • Test hypotheses about two population variances with the F-distribution.
