<span>They utilize and make use of the scientific method in order to have clear basis and evidence for their investigations. Research method is always used to answer every scientific inquiry and in gaining evidential data or knowledge. The scientific method has the following process or at least undergoes the process of
1. Observation</span> 
2. Hypothesis 
3. Experimentation 
4. Interpretation of data 
5. Evaluating the data 
6. Passing and recording the data 

<span>These steps are crucial and the empirical data that these scientists obtain are very important to keep that is why research paper, thesis and dissertations exists.<span>

The P value for the given data set is 25127. For finding P value, we have to must find the Z value.

<h3>How to get the z scores?</h3>

If we've got a normal distribution, then we can convert it to standard normal distribution and its values will give us the z score.

The Z value is calculated as;

Z = \dfrac{X - \mu}{\sigma})

Z = (X - μ) / σ

Z = (4.007 - 3.6) / 0.607

Z = 0.67051

The P value for the given data set is 25127.

Ivan

Answer: QUANTUM MECHANICAL MODEL OF THE ATOM.

Explanation:Edwin Schrodinger is an Australian Physicist,who proposed the Quantum mechanical model of an Atom,this theory helped to give a better understanding of Bohr's model.

According to Bohr's model,it is believed that electrons are concentrated around the circular shell of the Nucleus of an Atom which Edwin Schrodinger improved by proofing that the Behaviors of electrons around an the Nucleus of an Atom can be explained by the Mathematical representation of their waves.
