Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In a one-way ANOVA, if the computed F value exceeds the critical F value, what decision is made regarding the null hypothesis
A
Reject H0 since there is evidence of a treatment effect.
B
Do not reject H0 because a mistake has been made.
C
Reject H0 since there is evidence that all means differ
D
Do not reject H0 since there is no evidence of a difference
Explanation: 

Detailed explanation-1: -Answer and Explanation: If we perform a one-way analysis of variance and we come up that the computed F statistic is greater than the critical F value, then we can: b) reject the null hypothesis since there is evidence that not all the means are different.

Detailed explanation-2: -In a one-way ANOVA, if the computed F value exceeds the critical F value, what decision is made regarding the null hypothesis. Reject H0 since there is evidence of a treatment effect.

Detailed explanation-3: -A value of F=1 means that no matter what significance level we use for the test, we will conclude that the two variances are equal.
