<span>THe transition from elementary school to junior high school can be very tough for students. One would expect their academic achievement to drop. Usually, students earn lower grades in their first year of junior high school than they typically earned in grade school.

The null hypothesis makes a claim about population parameter. A null hypothesis is a statement about the value of a population parameter. So the correct answer is (a).
An example of a null hypothesis is one that asserts that no statistical significance can be found in a collection of provided observations. A hypothesis is tested using sample data to determine how plausible it is. It is represented as H0 and is occasionally referred to as simply the "null." To determine if a theory regarding markets, investment methods, or economies is correct or wrong, quantitative analysts employ the null hypothesis, often known as the conjecture. The alternate theory contends that there is a distinction.
Therefore correct answer is (a).

Answer:
No.
Explanation:
This is not the nineteenth century where there are housewives doing all the household chores whilst the men go off to work and provide for their family. Sure, there are some countries like Uruguay where the female children are taught they have to wash the dishes and fold and iron the clothes whereas if they have a brother, their brother does not. However, I do not find this rigtheous whatsoever. Everyone is equal; we should not discriminate or delegate tasks depending upon our genders.
