Answer:
The answer is below
Step-by-step explanation:
The procedure of selecting a sample is thus called, fulfilling two fundamental properties:
-All individuals in the population have the same probability of being elected.
-All samples of the same size are equally likely.
From a mathematical point of view, simple random sampling is performed assuming that the population has infinite elements. In practice, it is often the case that the populations to be considered have a very large number of elements, which can be compared to a situation with infinite elements.
Yes, it is possible to sample data instances using a distribution different from the uniform distribution.
In excel, do the following to obtain a sample dataset.
E.g. to create a 5 element sample from the standard normal distribution, place the formula = NORM.S.INV (RAND ()) in cell A1, highlight the range A1: A15 and press Ctrl-D.
 
        
             
        
        
        
Answer:

General Formulas and Concepts:

Integration
Integration Rule [Reverse Power Rule]:                                                           
Integration Rule [Fundamental Theorem of Calculus 1]:                                 
Integration Property [Multiplied Constant]:                                                     
Integration Property [Addition/Subtraction]:                                                   ![\displaystyle \int {[f(x) \pm g(x)]} \, dx = \int {f(x)} \, dx \pm \int {g(x)} \, dx](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Cint%20%7B%5Bf%28x%29%20%5Cpm%20g%28x%29%5D%7D%20%5C%2C%20dx%20%3D%20%5Cint%20%7Bf%28x%29%7D%20%5C%2C%20dx%20%5Cpm%20%5Cint%20%7Bg%28x%29%7D%20%5C%2C%20dx)
Area of a Region Formula:                                                                               ![\displaystyle A = \int\limits^b_a {[f(x) - g(x)]} \, dx](https://tex.z-dn.net/?f=%5Cdisplaystyle%20A%20%3D%20%5Cint%5Climits%5Eb_a%20%7B%5Bf%28x%29%20-%20g%28x%29%5D%7D%20%5C%2C%20dx)
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify.</em>
y = 2x + 3
<em>x</em>-interval [3, 4]
<em>x</em>-axis
<em>See attachment for graph.</em>
<u>Step 2: Find Area</u>
- Substitute in variables [Area of a Region Formula]:                                
- [Integral] Rewrite [Integration Property - Addition/Subtraction]:            
- [Integrals] Rewrite [Integration Property - Multiplied Constant]:            
- [Integrals] Integrate [Integration Rule - Reverse Power Rule]:                
- [Integrals] Integrate [Integration Rule - FTC 1]:                                        
- Simplify:                                                                                                      
∴ the area bounded by the region y = 2x + 3, x-axis, and the coordinates x = 3 and x = 4 is equal to 10.

Answer:
20%
Step-by-step explanation:
Think about it. 100 divided by 25 is four so just multiply 5 times 4 and you got 20. giving you the probability of 20%. Your Welcome! And I'm not a genius it's just simple math. 
 
        
             
        
        
        
Answer:
7.1
Step-by-step explanation:
Using the distance formula
d = sqrt (  (x2-x1)^2 + ( y2-y1)^2)
     sqrt (  (-5-2)^2 + ( -3- -2)^2)
     sqrt(   ( -7)^2  + ( -3 +2)^2)
    sqrt(   ( 49  + 1)
    sqrt( 50)
   7.071067812
