A. A processing line can combine unites of inputs(X) to produce units of output(Y) such that there • is a linear relationship between X and Y. Given the values of X and Y as follow: 7 5 2 Y 8 14 12 (1) Formulate a simple linear regression equation. (Hi) Determine the value of the correlation coefficient and interpret your result. (ii) Find the value of the coefficient of determination and interpret your results. (iv) What will be the output level if the input is 20? (v) What proportion of the variation in output is not due to X? (vi) Using a = 0.01 test whether the correlation between X and Y are positively linearly correlated. 6.

Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
