Using 2005 MLB, you examine factors affecting the number of wins. More specifically, you run the following regression as your baseline:  winsi = beta0 + beta1 x salarymili + beta2 x erai + beta3 x hri + beta4 x errori + beta5 x sbi  + ui   F test MLB.png Use regressions results above to answer the following questions. You want to test the following null hypothesis:  H0: beta1 = beta2 = beta3=beta4 = beta5 =0 against H1: At least one betaj (j=1, 2, …, 4, 5) is not zero.  The test statistic is [BLANK-1]. (You must round up your answer to two decimal points).  When the level of significance alpha is 0.05, the critical value is [BLANK-2] (You must round up your answer to three decimal points if needed).
