100%sure its right :)
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:
Descriptive research
Explanation:
If our goal is to estimate the prevalence of a disease or exposure in a population, we are talking about descriptive research. Whenever we are trying to describe the characteristics of a population or a phenomenon (in this case the frequency of a disease and exposure to it) we are doing a descriptive study. The results of this type of studies are usually represented in descriptive statistics and percentages. For example, from this sort of survey we would find out the percentage of population that suffer this disease.
I believe the correct answer from the choices listed above is option B. The average weather condition in an area over a long period of time is called climate. It is a statistical distribution of weather patterns when that change lasts for an extended period of time. Hope this answers the question.
