PART TWO: Make a second contingency table (Table 2) condensing contingency table 1 -using four Birth Order number categories: 1 or 2, 3 or 4, 5 or 6, 7 or 8, and five Piercing categories: 0, 1-2, 3-4, 5-6, 7 and above 01 - 23 - 45 - 6 7 and above 1 or 2 3 or 4 5 or 6 7 or 8 Show the complete Table 2 and answer these questions:0 1- 23 - 45 - 6 7 and above 1 or 2 3 or 4 5 or 6 7 or 8 Show the complete Table 2 and answer these questions: 1. Given that a person was either the first or second born in his/her family, what is the probability that (s)he has no piercings? 2. Given that a person was the third or fourth person born in his/her family, what is the probability that (s)he has 3 or more piercings?

If you do not agree that the choices were good, say why and suggest and show a better choice.PART ONE: Are birth order (1 to 8) and number of piercings (0 to 10) related? You are going to make a contingency table ('I'abie 1) comparing the number of piercings and the birth order. Use the following categories and put together the contingency table and then answer the questions below. I I! E E I! E E 7 6 7 8 9 10 piercing 0 birth order CO 10 11 12 9 10 11 12 13 14 co - c w 9 10 11 12 13 14 15 16 12 13 14 15 16 17 18 10 11 11 12 13 14 15 16 17 18 19 20 15 16 17 18 19 20 21 22 18 19 21 24 16 20 22 23 26 16 17 18 19 20 21 22 23 24 25
