What conditions are necessary in order to use a t-test to test the differences between two population means?.

Sliva [168]

The two samples must be independent and each must be drawn at random from any population. The two samples must be independent and each must be drawn at random from a healthy population.

At the very least, nominal scale data are required. There must be normal populations. There must be knowledge of the two population standard deviations. The samples depend on one another.

<u>What is nominal scale?</u>

A nominal scale is a measurement scale that is used to categorize events or things into distinct groups. This type of scale only needs one-of-a-kind identifiers to mark each separate category instead of requiring the usage of numerical values or categories ranked by class.

Through which microscope were cells first observed?

poizon [28]

Compound microscope

<h3>Further explanation</h3>

In 1665, Robert Hooke used a compound microscope to observe cells. Hooke observes the cell walls of dead plants (in the form of cork) when they appear under a microscope. He named it the cell because it looked similar to a cellula or small room inhabited by monks.

Development of microscopy:

1590: Hans and Zacharias Janssen, as Dutch lens grinders, mounted two lenses in a tube to produce the first compound microscope.
1660: Robert Hooke published <em>Micrographia</em>, containing detailed observations of biological materials made with the best compound microscope.
1676: Anton van Leeuwenhoek was the first person to observe a live cell under a microscope, i.e., the algae Spirogyra.
1931: Ernst Ruska constructed the first electron microscope. With the invention of the electron microscope, many infectious agents smaller than bacteria could be seen.

Until now, we can see how important the use of microscopes, especially in microbiology, that is the study of microorganisms.
