Question

The regression equation built for predicting the corrosion rate in steel plates form temperature, humidity, gas, and dust is found to be y = -92.94 – 1.58 temperature + 3.26 humidity + 1.37 gas + 1.36 dust. The number of observations considered in the study is 16. The standard error of the regression coefficients representing these four regressors are 0.8068, 0.8742, 0.8362, and 0.3747 respectively.

If you conduct a test on the individual regression coefficient Beta 1 using 0.05 level of significance (H0: Beta 1 = 0 vs. H1: not equal to 0), which of the following is correct about the P-value?
