Please help with these regression analysis problems :)

Consider the following confidence intervals computed in R, which of the following statements is TRUE 2.5 % 97 .5 % (Intercept) 2.25441102 3.560861459 TV 0 . 04314101 0. 048957162 Radio 0 . 17175798 0.208299001 Newspaper -0. 01516832 0. 008936575 o a. The null hypothesis that beta_Newspaper = 0 should NOT be rejected under a 0.05 significance level O b. These are prediction intervals o c. The higher the confidence level of a confidence interval is, the narrower the confidence interval would be o d. The confidence level for these confidence intervals is 99% Which of the followings is NOT TRUE about the F-test o a. F distribution is a symmetric distribution O b. For the global F-test, under the null hypothesis, the F-test statistic follows a F-distribution O c. F distribution is characterized by two parameters o d. The larger a model is, the smaller the residual degrees of freedom is
