water climbs up from the roots to the leaves of a tree without using any energy? what two properties of water allow this to happen. HELP ASAP PLZ

cohesion and adhesion

Explanation:

cohesion: water molecules stick to one another through and fill the column in the xylem and act as a huge single molecule of water (like water in a straw).

adhesion: water molecules adhere to the surface of a solid (surface of cell wall)

both of the properties enable capillary action to works (movement of the water) without a sucking force.

Specification of Null hypothesis, alternate hypothesis,setting level of significance, calculation of test statistics and P value, making conclusion.

Explanation:

When you are in a need to compare two or more groups in statistics, you have to use testing of hypothesis. There are two important things that is to be considered in the testing of hypothesis. First is the size of the sample that you choose and the extent of variability in the sample. This is useful for the determination of the differences that exists.

Testing of hypothesis helps in doing this. This can be done with the help of Five steps like, specification of Null and Alternate hypothesis. from this two, one will be selected at the conclusion. Then the next step will be, setting the level of significance. Third is the calculation of P value and the test statistics. This will be compared and at last, either Null or Alternate hypothesis will be selected.
