Question

answer the questions below.
(2) a computer manufacturer conducted a survey. it showed that a younger customer will not necessarily purchase a lower or higher priced computer. what is likely true?
there is no correlation between age and purchase price.
there is a correlation between age and purchase price. there may or may not be causation. further studies would have to be done to determine this.
there is a correlation between age and purchase price. there is probably also causation. this is because there is likely a decrease in the purchase price with a decrease in age.
(3) a hospital found that a lower outside temperature indicates a higher number of patient visits. what can we determine from this information?
there is no correlation between outside temperature and number of patient visits. however, there is no causation. this is because there is an increase in the number of patient visits with a decrease in the temperature outside.
there is a correlation between outside temperature and number of patient visits. there may or may not be causation. further studies would have to be done to determine this.
(4) mr. allen studied his students spanish test scores and sleeping habits. he found that students who slept less tended to earn lower scores on the test. what conclusion should he make?
there is no correlation between test score and amount of sleep.
there is a correlation between test score and amount of sleep. there is probably also causation. this is because there is a decrease in a students test score with a decrease in the amount of sleep.
there is a correlation between test scores and amount of sleep. there may or may not be causation. further studies would have to be done to determine this.

Explanation:

Step1: Analyze part (a)

The survey shows no clear - cut relationship between age and computer purchase price. So, there is no correlation. But correlation does not imply causation, and further studies are needed to determine causation.

Step2: Analyze part (b)

The hospital found that lower outside temperature is associated with a higher number of patient visits. There is a correlation, but we can't be sure about causation without further study.

Step3: Analyze part (c)

Mr. Allen found that students who slept less tended to earn lower test scores. There is a correlation, but we need more research to establish causation.

Answer:

(a) There is no correlation between age and purchase price. There may or may not be causation. Further studies would have to be done to determine this.
(b) There is a correlation between outside temperature and number of patient visits. There may or may not be causation. Further studies would have to be done to determine this.
(c) There is a correlation between test scores and amount of sleep. There may or may not be causation. Further studies would have to be done to determine this.
