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).

1. Deforestation: The Sub- Saharan Africa is occupied with scanty bushes and trees in the forest area. The climate is hot and dry. The removal of bushes and trees has resulted in deforestation and desertification in the region.
2. Wetland degradation: The discharge of agricultural drainage into the wetland has degraded the quality of water in the wetlands in Sub- Saharan Africa.
Answer:
The most likely cause of this disease is that siblings have a variable expression of this disease.
Explanation:
Neurofibromatosis 1 is an autosomal dominant disorder, even though it is a very rare disease to occur. This dominant nature causes this disease to be expressed even in people who have heterozygous alleles for it, which makes it easier for siblings to have this disorder, since only those who are hom0zygous recessive would not present it. However, the expressiveness of the disease may vary between siblings, as is the case shown above, where although the two siblings have the same disease, they present it in different ways.
