One-way analysis of variance is being used to test the equality of four population means using a sample of size 8 from each of the four populations.The test statistic (F_stat) for the test turns out to be 3.991.The significance level is set at 5%.Report your conclusion. A)Since the test statistic (F_stat) is greater than the critical value (F_c) for the test, we reject the "no difference" null hypothesis. B)Since the test statistic (F_stat) is less than the critical value (F_c) for the test, we cannot reject the "no difference" null hypothesis. C)Since the test statistic (F_stat) is greater than the critical value (F_c) for the test, we cannot reject the "no difference" null hypothesis. D)Since the test statistic (F_stat) is less than the critical value (F_c) for the test, we reject the "no difference" null hypothesis.

The decision to reject the null hypothesis in an ANOVA test depends on whether the test statistic exceeds the critical value at the chosen significance level. If the test statistic is greater than the critical value, it indicates that there is a statistically significant difference between the means, leading to the rejection of the null hypothesis that there is no difference.
