Florida has over 7700 lakes.¹ We wish to estimate the correlation between the pH levels of all Florida lakes and the mercury levels of fish in the lakes. It is found that the correlation between these two variables for a sample of size n=53 of the lakes is -0.575.

A)Give the notation for the quantity we are estimating.

The parameter of interest is _______

(b) Give the notation for the quantity we use to make the estimate. The best estimate is _____________

(c) Give the exact value of the best estimate. Best estimate =
