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.

Answer:
Which is faster, visual or auditory reaction times?
If the DNA sequences changes to:
AAT AGC ATGA
this would be an example of
an insertion mutation
a homozygous mutation
a deletion mutation
Natural Selection
Answer:
Insertion
Explanation:
this would be insertion because in the first part another A is added which is the cause for there being an extra part at the end and the new A in the first part
Answer:
The correct answer is because of gravity and air resistance.
Explanation:
When we speak of free fall, we are referring to something that falls "into the void", and which has no force to oppose such a fall.
Due to the gravity and atmosphere of our planet, this situation is not possible. When an object falls close to our surface, it is very difficult to do it in free fall. Gravity is going to pull this object down, which along with air resistance, will cause the object to fall at a constant speed.
Answer : The electrocardiogram records the electrical signals of heart.
Explanation :
Electrocardiogram : It is a type graph that records the electrical signals or rate of the heart. It is also called ECGs.
It is a common test that is used to detect the problems in heart and also monitor the status of the heart in many conditions.
During the ECG, sensors (electrodes) that can detect the electrical activity of the heart are attached to the chest.
Hence, the type of data recorded by the electrocardiogram is the electrical signals of heart.
An electrocardiogram records the electrical activity of the heart.
