Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
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.

SECOND PART
a. Let P be the true population correlation coefficient
H0 =P =0
a 0.05, df=n-2, Critical Value (refer the table )
H1 = P #0
b. T statistics = T Value
r - P
1-r2
V n - 2
c. Decision
If t value is less than critical value or more than critical value. H0 is rejected.
Otherwise it Is fail to reject
