      The ANOVA for the full multiple regression shows a p-value equal to 0.0000, thus Ho can be rejected (because the p-value is less than ( of 0.05). Since the null hypothesis may be rejected, there is sufficient evidence of a relationship (or, an association) between selling price and the three explanatory variables in the sample of 50 houses.

      P-Value = 0.000. This tells us that the sample estimates of Pearson correlation of Day and Weight is -0.998 based on 14 observations. When test for significance, a low p-value rejects the null that rho=0 and we conclude that the sample estimates just did not come from the noise. There is a meaningful linear relationship between the two variables.

      To interpret the t-test results, all you need to find on the output is the p-value for the test. To do an hypothesis test at a specific alpha (significance) level, just compare the p-value on the output (labeled as a “Sig.” value on the SPSS output) to the chosen alpha level. Alternatively, you could just report the p-value, rather than ...
