Based on the data in the table above:
b) Find the correlation coefficient between hydrocarbon levels and oxygen purity]
d) Provide a regression equation
e) Use the regression equation to predict:
(i). Oxygen purity when hydrocarbon level is 2
(ii). Hydrocarbon level when Oxygen purity is 80%.

The correlation coefficient between hydrocarbon levels and oxygen purity correlation is: 0.5347465

regression equation ∴ Y = 81.969 + 8.501X

(i). Oxygen purity when hydrocarbon level is 2
