INVESTIGATING STATISTICAL CONCEPTS, APPLICATIONS, AND METHODS

ERRATA

(these errata reflect changes that were not made in the first edition)

 4/11/07 p. 86, exercise 9 has an extraneous paragraph: “Studies have shown…” 5/31/06 p. 471, exercise 11 should refer to exercise 45 of Chapter 1 5/22/06 p. 325, part (k), should refer to the Brown study, not the kissing study 4/18/06 p. 112, part (o), Minitab comment should refer to logten (no space between log and ten) 4/11/06 p. 103, line 2 of Investigation 2.1.2, delete extra “of” before “rainfall” 4/11/06 p. 66, part (j), m should be M 4/11/06 p. 70, part (s), need a blank space between < and )? to enter a numerical value 11/14/05 p. 235, Summary box, the confidence interval discussion should refer to (1-C) not (1-C)/2 11/4/05 p. 235, Practice Problem 3.3.6(b), use .50 instead of .10 (10/28) 10/14/05 p. 83, Exercise 11, the text should read "5 of the 15 females died" 9/28/05 p. 85, Exercise 15(a), the end of the first sentence should refer to the "non-smoker group" 9/14/05 p. 65, part (i), m should be M 9/.8/05 p. 66, box, line 2, m should be M 9/4/05 p. 404, Exercise 62, while part (b) can be done with the applet, parts (c) and (d) cannot.  We suggest using a Minitab macro to perform the simulations as in Investigation 4.4.2.  To generate random data from the different distributions, use, for example, random 15 c1;                 #where 15 is the sample size, results are stored in C1 and then specify the distribution of choice (and parameter values) in a single subcommand line, e.g., normal 10 5. uniform 0 50. expo 25. 8/22/05 p. 447, part (a), there should not be a space in the SleepDeprivation.mtw file name

Prior to August

p. 145, part (k), in the macro, for consistency, use let c6(k1)=mean(c5)-mean(c4)

then in part (m), use let c8=(c6>=15.92)

p. 148,
after (r), the graph can shade to the right of 15.92 instead of to the left of -15.92

p. 321, Investigation 4.3.5 should refer back to Investigation 4.3.3

p. 380
, Example 4.2, in Confidence Intervals section, the S symbols in the confidence interval calculations should be implication symbols

p. 422, paragraph after h, line 4: the 1.48 should be 1.59

p. 469, exercise 3, part (d) could refer to this as the randomization distribution instead of the sampling distribution

p. 582, exercise 29, the data file for “ComparingDietsFull.mtw” on the CD does not contain all of the necessary variables to complete Exercise 29.  A newer version of the data file can be download from the ISCAM Data Files page.
