The answer is: directional research hypothesis
directional research hypothesis is a form of prediction that initiated in order to guess whether two variables would experience some sort of positive or negative changes. In the example above, boys and girls are the variables and whether they agree or disagree with school rules are the changes.
Answer:
directional research hypothesis
Explanation:
As a plant grows, its mass increases. The matter that makes up this new mass comes mostly from air and water that the plant changes into organic compounds such as cellulose using the energy from sunlight.
As an animal grows, its mass increases. The matter that makes up this new mass comes mostly from
A.
air and water that the animal changes into organic compounds using the energy from sunlight.
B.
organic compounds that the animal breaks down into water and carbon dioxide.
C.
substances that the animal has eaten but cannot digest.
D.
food that the animal has eaten and changed into other organic compounds.
The correct answer is D. Food that the animal has eaten and changed into other organic compounds.
Explanation:
Different from plants, that use water, carbon dioxide, and sunlight to create organic compounds and obtain energy, animals need to consume food that depending on the animal includes plants, other animals or both. Additionally, once an animal consumes food this is digested by specialized organs and cells and changed into organic compounds, this includes carbohydrates, lipids, protein, and nucleic acids that are necessary for organisms to obtain energy, grow and live. According to this, as an animal grows its mass increases, and the matter that makes up this new mass comes mostly from food the animal eats and changes into organic compounds (Option D).
A set of all possible data values for a subject under consideration is called ___.

Invent a sample of size 5 for which the sample mean is 20 and the sample median is 15
The sample mean is calculated as (10+12+15+30+35)/5 = 20, and the sample median is 15, which is the middle value when the data is sorted in ascending order.
What is sample median?The sample median is the sorted sample's middle value. The median is the middle value if the sample size is odd. The median is the average of the two middle values if the sample size is even.
The median is the value that separates the upper and lower halves of a data sample, population, or probability distribution in statistics and probability theory.
Here is one possible size 5 sample that meets the given criteria:
{10, 12, 15, 30, 35}
When the data is sorted in ascending order, the sample mean is calculated as (10+12+15+30+35)/5 = 20, and the sample median is 15, which is the middle value.
Thus, this can be a sample of size 5 for which the sample mean is 20 and the sample median is 15.
