Using a random sample with 100 observations, the regression of Y on X andW yields an R-squared of 3%.Then the homoscedasticity-only F-statistic testing the joint significance of Xand W's coefficients is given by ______with a p-value ________________than 5% (use "greater" or "smaller").This suggests that the coefficients of X and W are jointly_____________ at 5% level. (use "significant" or "insignificant").Treat the sample size as large when answering the questions.Critical values for chi-squared(q)/q: when q = 1; 3.84 (5 % level), 6.63 (1% level): when q = 2: 3.00 ( 5 % level), 4.61 ( 1% level): when q = 3; 2.60 (5% level),3.78 (1% level).
