The null hypothesis to test the significance of is:
R: General Linear Hypotheses - Lugos
CORRECTION: The feats accomplished through the application of scientific knowledge are truly astounding. Science has helped us eradicate deadly diseases, communicate with people all over the world, and build that make our lives easier everyday. But for all scientific innovations, the costs must be carefully weighed against the benefits. And, of course, there's no guarantee that solutions for some problems (e.g., finding an HIV vaccine) exist though science is likely to help us discover them if they do exist. Furthermore, some important human concerns (e.g. some spiritual and aesthetic questions) cannot be addressed by science at all. Science is a marvelous tool for helping us understand the natural world, but it is not a cure-all for whatever problems we encounter.
Testing a General Linear Hypothesis in R - Stack Overflow
This section discusses hypothesis tests on the regression coefficients in multiple linear regression. As in the case of simple linear regression, these tests can only be carried out if it can be assumed that the random error terms, , are normally and independently distributed with a mean of zero and variance of .Three types of hypothesis tests can be carried out for multiple linear regression models:
It is Multivariate General Linear Hypothesis
CORRECTION: This misconception likely stems from introductory science labs, with their emphasis on getting the "right" answer and with congratulations handed out for having the "correct" hypothesis all along. In fact, science gains as much from figuring out which hypotheses are likely to be wrong as it does from figuring out which are supported by the evidence. Scientists may have personal favorite hypotheses, but they strive to consider multiple hypotheses and be unbiased when evaluating them against the evidence. A scientist who finds evidence contradicting a favorite hypothesis may be surprised and probably disappointed, but can rest easy knowing that he or she has made a valuable contribution to science.

where is the regression mean square and is the error mean square. If the null hypothesis, , is true then the statistic follows the distribution with degrees of freedom in the numerator and ( ) degrees of freedom in the denominator. The null hypothesis, , is rejected if the calculated statistic, , is such that:
