Please answer step by step, applying correlation and simple
linear regression formulas, use of tables, as well as any
assumptions needed to solve the problems. The previous answer you
provided me was incomplete. I need calculations and formulas.
The following sample observations were randomly selected:
X: 5 3 6 3 4 4 6 8
Y: 13 15 7 12 13 11 9 5
1. Consider the following aspects when submitting your test:
o Determine the correlation coefficient
o Determine the regression equation
o Find the value of the dependent variable when X = 4.
2. Present your answers with what you have learned so far about
correlation and simple linear regression. Show all your
calculations, formulas and interpretations.
