Question

A study is given in which scientists examined data on mean sea surface temperatures (in degrees Celsius) and mean coral growth (in millimeters per year) over a several-year period at different locations. (Sea surface temperature is x and growth is y.)

Sea Surface Temperature 29.67 29.88 30.17 30.22 30.47 30.64 30.80

Growth                               2.64 2.59 2.67 2.50 2.49 2.39 2.26

(a) Find the regression equation. (Round your answers to three decimal places.) ŷ = + x

(b) Say in words what the numerical value of the slope tells you. (Round your answer to three decimal places.) Every increase of one degree Celsius means about ______ fewer mean millimeters of coral growth per year.

Answer 1

a) Regression equation is,

Regression equation = -0.311 + 11.928(X)

B)every increase of one degree Celsius means about 11.928 fewer mean millimeters of coral growth per year.
