The student was likely investigating the distribution of homework nights during a week, and should use a chi-square test of independence to analyze the data.
The student was most likely investigating the nights during which the highest number of students do the majority of their homework with equal frequencies during a week. This question relates to analyzing the distribution of homework nights throughout the week. To test this hypothesis, the student should use a chi-square test of independence, which compares the observed frequencies with the expected frequencies.
The chi-square test is a statistical method used to determine if there is a significant association between categorical variables. It compares the expected and observed frequencies in a contingency table, assessing whether any deviations are due to random chance or reflect a true relationship.

If a drug controls blood pressure than the transport of materials throughout our body will be affected. As for example - gases exchange, hormone level of every organ will be affected most. organs can develop hypoxia or hyperoxia conditions which can lead to cell damage or malfunction inside the organ and that can have a lethal effect on body also.
Answer:Natural selection is the process in nature by which organisms better adapted to their environment tend to survive and reproduce more than those less adapted to their environment.For example, tree frogs are sometimes eaten by snakes and birds. Gray Tree frogs blend well in dark wooded areas on tree bark and Green Tree frogs blend in well with green vegetation found in marshes and swamps. A Green Tree frog on the bark of a tree is easier for a predator to find, compared to a Green Tree frog on a green leaf. So, Green Tree frogs that go into habitats where they are not camouflaged are more likely to be eaten by predators. Since Tree frogs that have been eaten do not live to have any more baby Tree frogs, natural selection has favored Tree frogs that live in habitats in which they are more camouflaged.
Answer:
In a habitat there are red bugs and green bugs. The birds prefer the taste of the red bugs, so soon there are many green bugs and few red bugs. The green bugs reproduce and make more green bugs and eventually there are no more red bugs.
