The F-test statistic should be calculated to determine if the null hypothesis should be rejected or not. If the calculated F-value is greater than the critical F-value, then the null hypothesis should be rejected, indicating that at least one mean is different. Since the F-value is not given, it cannot be determined if the null hypothesis should be rejected or not.
