In a study analyzing data from 400 companies, the relationship between a company's total earnings (Yi) and the average number of years of experience of its workers (Xi) is modeled by the following linear regression equation: Yi = β1 + β2 * Xi + Ei for i = 1, 2, ..., 400 A financial analyst aims to test the joint null hypothesis that both coefficients β1 and β2 are equal to zero, at a 95% confidence level. The p-value associated with the t-statistic for β1 is 0.07, the p-value associated with the t-statistic for β2 is 0.06, and the p-value for the F-statistic of the overall regression model is 0.045.
