In a dataset comprising 400 companies, the relationship between the total income of a company (Yi) and the average years of experience per employee (Xi) is represented by the following linear regression equation: Yi = β1 + β2*Xi + Ei, where i ranges from 1 to 400.

A researcher aims to test the joint null hypothesis that both β1 and β2 are equal to zero, using a 95% confidence level. The p-value associated with the t-statistic for β1 is 0.07, the p-value for the t-statistic for β2 is 0.06, and the p-value for the F-statistic for the overall model is 0.045.
