(a) A piano instructor examined student progress. He noticed that when students spend less time playing video games, their memorization ability tends to increase. What can he conclude? O There is no correlation between amount of time spent playing video games and memorization ability. O There is a correlation between amount of time spent playing video games and memorization ability. There may or may not be causation. Further studies would have to be done to determine this. O There is a correlation between amount of time spent playing video games and memorization ability. There is probably also causation. This is because there is an increase in memorization ability with a decrease in the amount of time spent playing video games. (b) An environmental study was conducted. It reported that houses with more inhabitants do not necessarily produce more or less trash. What can be determined? O There is no correlation between number of inhabitants and amount of trash produced. O There is a correlation between number of inhabitants and amount of trash produced. However, there is no causation. This is because there is probably an increase in the amount of trash produced with an increase in the number of inhabitants. O There is a correlation between number of inhabitants and amount of trash produced. There may or may not be causation. Further studies would have to be done to determine this. (c) Data was collected at a pool. It showed that being older does not imply that a swimmer will stay for a shorter or longer amount of time. What is likely true? O There is no correlation between age and length of stay. O There is a correlation between age and length of stay. There may or may not be causation. Further studies would have to be done to determine this. O There is a correlation between age and length of stay. However, there is no causation. This is because there is likely an increase in the length of stay with a decrease in age.

Question
Transcribed Image Text:(a) A piano instructor examined student progress. He noticed that when students spend less time playing video games, their memorization
ability tends to increase. What can he conclude?
O There is no correlation between amount of time spent playing video games and memorization ability.
O There is a correlation between amount of time spent playing video games and memorization ability. There may or may not be causation. Further
studies would have to be done to determine this.
O There is a correlation between amount of time spent playing video games and memorization ability. There is probably also causation. This is
because there is an increase in memorization ability with a decrease in the amount of time spent playing video games.
(b) An environmental study was conducted. It reported that houses with more inhabitants do not necessarily produce more or less trash.
What can be determined?
O There is no correlation between number of inhabitants and amount of trash produced.
O There is a correlation between number of inhabitants and amount of trash produced. However, there is no causation. This is because there is
probably an increase in the amount of trash produced with an increase in the number of inhabitants.
O There is a correlation between number of inhabitants and amount of trash produced. There may or may not be causation. Further studies would
have to be done to determine this.
(c) Data was collected at a pool. It showed that being older does not imply that a swimmer will stay for a shorter or longer amount of time.
What is likely true?
O There is no correlation between age and length of stay.
O There is a correlation between age and length of stay. There may or may not be causation. Further studies would have to be done to determine this.
O There is a correlation between age and length of stay. However, there is no causation. This is because there is likely an increase in the length of stay
with a decrease in age.
