Data on the weekly sales of room air conditioning units were matched with the average temperature and calculations produced sample correlation coefficients, r, in the range of –0.75 and –0.83. which of the following statements best expresses a conclusion that can be drawn from the values of r?

this cannot be determined from the information given.
as the temperature decreases, the number of room air conditioners sold decreases.
there is no relationship between temperature and sales.
as the temperature increases, the number of room air conditioners sold decreases.

D. As the temperature increases, the number of room air conditioners sold decreases.

Explanation:

As the temperature increases, the number of room air conditioners sold decreases.

Data on the weekly sales of room air conditioning units were matched with the average temperature and calculations produced sample correlation coefficients, r, in the range of –0.75 and –0.83. Since, the correlation coefficients are negative there is an inverse relation between the two quantities therefore As the temperature increases, the number of room air conditioners sold decreases.

well, you would divide 135 by 33 to get your answer. then that is how many seconds it would take. boardman should fly about 132 m or 4.090909090909091 seconds.
