The shoe sizes for two basketball teams are evaluated for their size. The graph compares the two teams. Which of the following can be concluded from the graph?

• The means for the two groups are the same. Since the data are skewed right, the range for Rockets appears greater. Therefore, a player selected at random from the Rockets is likely to have a greater shoe size than a player from the Spurs

• The medians for the two groups are the same. Since the data are skewed right, the mean for Rockets appears greater. Therefore, a player selected at random from the Rockets is likely to have a greater shoe size than a player from the Spurs

• The median for the two groups are the same. Since the data are skewed right, the range for Rockets appears greater. Therefore, a player selected at random from the Spurs is likely to have a greater shoe size than a player from the Spurs

• The means for the two groups are the same. Since the data are skewed right, the median for Rockets appears greater than the median of the Spurs. Therefore, a player selected at random from the Rockets is likely to have a greater shoe size than a player from the Spurs

A textbook is made up of 3 chapters

Chapter 1 is 35 pages

Chapter 2 is 70 pages

Chapter 3 is 45 pages

Nathan opens the book to random pages and records the chapter number. He repeats this process 50 times. The results are shown in the table

• Of Nathan's trials, 40% resulted in turning to Chapter 2

• The theoretical value of turning to chapter 3 is 0.3

• If Nathan repeated his experiment 80 times he would open his book to Chapter 1 exactly 19 times

• Nathan made a mistake because the observed relative frequency for opening the book to a page in chapter 2 is 40%.

• The observed relative frequency of opening the book to a page in chapter 3 is larger than the theoretical probability.
