  2. Section 2.1 Example 1

  3. Section 2.1 Example 2

  4. Figure 2.1The normal distribution: Y~N(m ,s2).

  5. Section 2.2 Example 6

  6. Figure 2.2An unbiased estimator has a sampling distribution that is centered over the population parameter. Yis unbiased because its sampling distribution is centered over m.

  7. Figure 2.3The estimator is asymptotically unbiased; its sampling distribution becomes centered over s2 as n→∞.

  8. Figure 2.4The variance of Ydecreases as the sample size increases.

  9. Figure 2.5The comparative efficiency of three estimators.

  10. Figure 2.6Simulated samplingdistributions (uniformpopulation).

  11. Figure 2.7Yi~ i.i.d.(m,s2).

  12. Figure 2.8The least squares estimator is the value of m that minimizes the sum of squares function S.

  13. Figure 2.9p-value for Example 10.

  14. Figure 2.10Rejection regions.

  15. Figure 2.12Yis lognormally distributed: ln Y~N(m , s2).

  16. Figure 2.13Simulated samplingdistributions for the statistict = √n(Y − m)/sunder nonnormality.
