The student will compare and contrast empirical data from a random number generator with the uniform distribution.
Collect the data
Use a random number generator to generate 50 values between zero and one (inclusive). List them in
[link] . Round the numbers to four decimal places or set the calculator MODE to four places.
Complete the table.

Calculate the following:
_______
s = _______
first quartile = _______
third quartile = _______
median = _______
Organize the data
Construct a histogram of the empirical data. Make eight bars.
Construct a histogram of the empirical data. Make five bars.
Describe the data
In two to three complete sentences, describe the shape of each graph. (Keep it simple. Does the graph go straight across, does it have a V shape, does it have a hump in the middle or at either end, and so on. One way to help you determine a shape is to draw a smooth curve roughly through the top of the bars.)
Describe how changing the number of bars might change the shape.
Theoretical distribution
In words,
X = _____________________________________.
The theoretical distribution of
X is
X ~
U (0,1).
In theory, based upon the distribution
X ~
U (0,1), complete the following.
μ = ______
σ = ______
first quartile = ______
third quartile = ______
median = __________
Are the empirical values (the data) in the section titled
Collect the Data close to the corresponding theoretical values? Why or why not?
Plot the data
Construct a box plot of the data. Be sure to use a ruler to scale accurately and draw straight edges.
Do you notice any potential outliers? If so, which values are they? Either way, justify your answer numerically. (Recall that any DATA that are less than
Q1 – 1.5(
IQR ) or more than
Q3 + 1.5(
IQR ) are potential outliers.
IQR means interquartile range.)
Compare the data
For each of the following parts, use a complete sentence to comment on how the value obtained from the data compares to the theoretical value you expected from the distribution in the section titled
Theoretical Distribution .
minimum value: _______
first quartile: _______
median: _______
third quartile: _______
maximum value: _______
width of
IQR : _______
overall shape: _______
Based on your comments in the section titled
Collect the Data , how does the box plot fit or not fit what you would expect of the distribution in the section titled
Theoretical Distribution ?
Discussion question
Suppose that the number of values generated was 500, not 50. How would that affect what you would expect the empirical data to be and the shape of its graph to look like?
Bacteria doesn't produce energy they are dependent upon their substrate in case of lack of nutrients they are able to make spores which helps them to sustain in harsh environments
_Adnan
But not all bacteria make spores, l mean Eukaryotic cells have Mitochondria which acts as powerhouse for them, since bacteria don't have it, what is the substitution for it?
Assimilatory nitrate reduction is a process that occurs in some microorganisms, such as bacteria and archaea, in which nitrate (NO3-) is reduced to nitrite (NO2-), and then further reduced to ammonia (NH3).
Elkana
This process is called assimilatory nitrate reduction because the nitrogen that is produced is incorporated in the cells of microorganisms where it can be used in the synthesis of amino acids and other nitrogen products
There are nothing like emergency disease but there are some common medical emergency which can occur simultaneously like Bleeding,heart attack,Breathing difficulties,severe pain heart stock.Hope you will get my point .Have a nice day ❣️

define infection ,prevention and control
Innocent
I think infection prevention and control is the avoidance of all things we do that gives out break of infections and promotion of health practices that promote life
