Question

legomyego180 · Answer

It is either C or D. Slope is negative so you have an inverse relationship. Not sure what a correlation coefecient is

ilovepuppieslol · Answer

how come nobody knows about that

legomyego180 · Answer

What level math is this? Highschool stats? Do you know summations? (The E looking symbol)

ilovepuppieslol · Answer

algebra 1 honors

legomyego180 · Answer

Are you allowed to use calculators on the test?

ilovepuppieslol · Answer

yes

legomyego180 · Answer

The answer is C. If the slope is negative the correlation coefecient is negative. If the slope is positive the coeficient is positive. If the Slope = 0 then your correlation coeficcient is also 0.

Go here and enter the data if you want to crank out the correlation coefficient. http://www.alcula.com/calculators/statistics/correlation-coefficient/

directrix · Answer

If you look at the data with the x values in order from small to large, you can see that as x gets larger, the corresponding y values get smaller and smaller.

That indicates that the line has a negative slope which means that the correlation coefficient have to be negative.

Option C is the only option with a negative correlation coefficient.  @ILovePuppiesLol
