Tests for significance of the computed intercept and computed slope are required in order to be able to predict the value of the dependent variable based on some value of the independent variable. The test used for this is the:
A) Chi-square.
B) Analysis of residuals.
C) t test.
D) f test.
E) z test.

The test typically used to evaluate the statistical significance of the intercept and slope in linear regression is the t-test, which assesses whether the estimated coefficients are significantly different from zero based on their standard errors. The other options (Chi-square, analysis of residuals, f-test, z-test) are either not applicable in this context or not commonly used for this purpose.
