The correct answer is: [C]: " -5 ΙxΙ = 25 " .
______________________________________________
In this answer choice, when you divide each side by "-5" ;
you get: " ΙxΙ = -5 ;
If x = 5, the result is "5" ; NOT "-5" .
If x = -5, the result is "5" ; NOT "-5" .
The "absolute value" of a value is always "zero" or greater.

Answer:
1. The null hypothesis is that there is no difference between the population means (in other words, there is no treatment effect).
2. The<u> alternative hypothesis</u> is that at least one of the population means is different from another (in other words, there is an effect Of at least one Of the treatments).
Step-by-step explanation:
In a statistical analysis, the statistician shares his participants into several groups and administers treatments to them. After administering the treatment, he might want to compare the values obtained to see if there is a difference. If he accepts the null hypothesis as true, that means that there was no difference between the population means. This can also be taken to mean that the result had no difference among the groups.
But if the alternative hypothesis was true, that means that the population means were not all equal and so, there was an effect from the treatment administered.
