Answer:
Since we know that the probability that a randomly selected student has at least 1 household member who smokes is 0.421. Then the total who correspond to Cell 8 on this case is 0.421*1000 = 421
Step-by-step explanation:
We assume the following table:
No Hou. smokes >=1 hou. smokes Total
______________________________________________________
Student indicates he Cell 1 Cell 2 Cell 3
or she has asthma
_______________________________________________________
Student indicates he
or she does not have Cell 4 Cell5 Cell 6
asthma
_______________________________________________________
Total Cell 7 Cell8 1000
We are assuming a grand total of 1000 people for this case
