Section 7.1 – Inference for the Mean of a Population

  1. Student's t Distribution - http://www.econtools.com/jevons/java/Graphics2D/tDist.html
    This applet compares the graphs of the t distribution with the normal curve.
  2. One Sample Hypothesis t-Test - http://www.kuleuven.ac.be/ucs/java/index.htm
    (Click on link). This applet simulates the one-sample t-test.
  3. Level of Significance of a Test: the One-sample t Statistic - http://stat.tamu.edu/~jhardin/applets/signed/LevelT.html
    This Then the lab simulates samples from a population. For each sample, the lab caculates the value of the test statistic, then draws a histogram of the one-sample t values and superimposes theoretical curve. Finally, it shades in the critical region (or regions if a two-sided test) under the curve, displays the critical values and the proportion of the statistics that would lead to rejection of H_o.
Section 7.2 – Comparing Two Means
- online resources:
  1. Two Sample Hypothesis t-Test - http://www.kuleuven.ac.be/ucs/java/index.htm
    (Click on link). This applet simulates the two-sample t-test.
