2. Write #8.37, 9.2, 9.5, 9.6, and the questions below.

3.(a) For #9.5 and 9.6, what is the symbol you should attach to the estimate in each case?
   (b) Which estimate, the estimate for #9.5 or the estimate for #9.6, comes from a sampling distribution having the smaller s.d.? Why?
   (c) Compute the estimated s.d. of the sampling distribution for the statistic of interest in #9.5.
   (d) Compute the estimated s.d. of the sampling distribution for the statistic of interest in #9.6.

4. The sampling distribution’s estimated s.d. in #9.5 and 9.6 has a name. It is called the standard error of the statistic. What abbreviation is used for standard error?

5.(a) The illustration (Figure 9.4) on p. 487 shows that out of 100 randomly simulated 95% confidence intervals for the parameter p, only _______ actually captured the true value of p. (Fill in the blank.)
   (b) Is the situation in part (a) a mistake in the textbook? Explain briefly.

 

Th 2/7/13

HW due: Write #9.10 on p. 482, #9.12 on p. 492, #9.14 on on p. 493, and #9.24 and 9.26 on p. 494.
