For a sample of 400 firms, the relationship between corporate revenue (Yi) and the average years of experience per employee (Xi) is modeled as follows:
You wish to test the joint null hypothesis that at the 95% confidence level. The p-value for the t-statistic for β1 is 0.07, and the p-value for the t-statistic for β2 is 0.06. The p-value for the F-statistic for the regression is 0.045. Which of the following statements is correct?
老师您好，希望可以有更详细的解释，我觉得p value，0.07 和0.06都比95置信区间的单尾2.5%要大，所以拒绝原假设。然后我不明白f检验的pvalue是什么意思，f是不是应该越大越拒绝咩
