  • Page 487: In Exercise 10.47 "Dominance of Politicians" the data show the dominance scores for male and female politicians. Part a asks to run a permutation test to see whether there is a difference in the ratings on competence between female and male speakers. Please replace "competence" by "dominance" in this sentence. (The data on the book's website, in addition to the dominance scores also contain a column for perceived competence. Using these as the responses, one does not find a significant difference between the distribution of competence scores for males and females, while the distributions of dominance scores are significantly different.)

  • Page 85: Exercise 112. There is an "e" missing at the end in "Hurrican" in the title of the Histogram.
  • Page 459: The numbers in the X and N columns of the displayed computer output need to be switched, as follows:

             Sample           X         N     Sample p

  • Page 42: The "100" x-axis label for histogram on the top of page 42 should really be "160", as shown below:

  • Page 44: "everyday" in the label of the bar graph on the very bottom should read "every day".
  • Page 76: Exercise 2.82. The two outliers are not discernible for the CO2 values for Central & South America. There really should be two symbols (almost on top of each other) to label the outliers, as in the boxplot below. In addition, the typo that read "Emmissions" for the y-axis label was corrected:


  • Page 201: In the box for Activity 1, very last paragraph: The "it's" should be "its" as in "After each click, the cumulative proportion of 6s will tend to fall closer and closer to its expected value of 1/6."
  • Page 222, Table 5.3: The total shown in the margin for row "More than $1,000,000" should be 0.00249 and not 0.00222.
  • Page 118: Beginning of line 3, second paragraph: The +2.61(0.267) should be a +26.1(0.267) since the estimated slope is 26.1 and not 2.61. The final result of that equation is correct, though.
  • Page 353, Exercise 8.28: "The exercise should read like this: Using the Explore Coverage web app, let’s check that the large-sample confidence interval for a proportion may work poorly with small samples. In the app, set p = 0.30, n = 10 and leave the confidence level at 95%." Early versions of the 4th edition refer to the Explore Coverage Tab of the Inference for a Proportion App, which is now a stand-alone app.
  • Page 363: The answers to parts b and c of Exercise 8.33 in the back of the book are not in the correct order.
