Florida has over 7700 lakes. the correlation between ph level of a sample of 53 lakes and the mercury level of fish in these lakes is -0.575.

give notation for the quantity we are estimating, i. e. the parameter of interest.

give notation for the quantity we use to make the estimate and its value.

why can't we get an exact value, but only an estimate

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
