Answer:
Null hypothesis: male and female spiders organized in mating pairs don't differ significantly in respect to body length
Alternative hypothesis: male and female spiders organized in mating pairs exhibit significant differences in respect to body length
The application of one statistical test in order to obtain one p-value (probability value) may provide useful evidence to support the alternative hypothesis (or reject it).
The inference procedure uses the information collected from the sample in order to obtain one conclusion. Frequentism is a type of inference procedure that can be used to test a hypothetical test case, which is here represented by male and female spiders organized in mating pairs.
The biologists have categorized protozoans as a part of Kingdom Protista, they have attempted to sort protists in comparison to three of the other kingdoms, that is, animals, plants, and fungi. However, this has not worked as several of the protists demonstrate features from two or more of these kingdoms.
The protozoans show considerable diversity, that is, some live as predators, some as parasites, and some others are thriving as producers. Scientists have attempted to categorize the organisms within the protists as either fungus-like, plant-like, or animal-like.
However, close testing and genetic examination have shown that these classifications often does not imply.
