同学你好，你应该问的是解答里面最后一句话吧，他这个是个定语从句，后面这个“all regression coefficients are equal to 0”是用来修饰前面的原假设的，而不是最终的拒绝原假设的结论。

如果你问的问题不是这个点，欢迎继续追问~

NO.PZ201512020300000401问题如下 1. Regarng the intern’s Question 1, is the regression mol a whole significant the 0.05 level?A.No, because the calculateF-statistic is less ththe criticvalue for F.B.Yes, because the calculateF-statistic is greater ththe criticvalue for F.C.Yes, because the calculateχ 2 statistic is greater ththe criticvalue for [#PZMATH172#].B is correct.The F-test is useto termine if the regression mol a whole is significant.F = Mesquare regression (MSR) ÷ Mesquareerror (MSE)MSE = SSE/[n – (k + 1)] = 19,048 ÷ 427 = 44.60MSR = SSR/k = 1071 ÷ 3 = 357F = 357 ÷ 44.60 = 8.004The criticvalue for grees of freem of 3 an427 with α=0.05 (one-tail) is F = 2.63 from Exhibit 5. The calculateF is greater ththe criticvalue, anChiesa shoulrejethe null hypothesis thall regression coefficients are equto zero. 本题中为什么2是427？1和2分别指什么什么数值？

B is correct.The F-test is useto termine if the regression mol a whole is significant.F = Mesquare regression (MSR) ÷ Mesquareerror (MSE)MSE = SSE/[n – (k + 1)] = 19,048 ÷ 427 = 44.60MSR = SSR/k = 1071 ÷ 3 = 357F = 357 ÷ 44.60 = 8.004The criticvalue for grees of freem of 3 an427 with α=0.05 (one-tail) is F = 2.63 from Exhibit 5. The calculateF is greater ththe criticvalue, anChiesa shoulrejethe null hypothesis thall regression coefficients are equto zero. 老师 这题是不是可以直接用P-value 来判断，所有X的P-value都小于0.01 那就说明都是significant？ 另外想我问下 α=0.05是因为下面图表上标明了是0.05就直接认为是这题的α是0.05么？
