The student will compare empirical data and a theoretical distribution to determine if data from the experiment follow a continuous distribution.
Collect the data
Measure the length of your pinky finger (in centimeters).
Randomly survey 30 adults for their pinky finger lengths. Round the lengths to the nearest 0.5 cm.

Construct a histogram. Make five to six intervals. Sketch the graph using a ruler and pencil. Scale the axes.
Calculate the following.
= _______
s = _______
Draw a smooth curve through the top of the bars of the histogram. Write one to two complete sentences to describe the general shape of the curve. (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?)
Analyze the distribution
Using your sample mean, sample standard deviation, and histogram, what was the approximate theoretical distribution of the data you collected?
X ~ _____(_____,_____)
How does the histogram help you arrive at the approximate distribution?
Describe the data
Using the data you collected complete the following statements. (Hint: order the data)
Remember
(
IQR =
Q3 –
Q1 )
IQR = _______
The 15
th percentile is _______.
The 85
th percentile is _______.
Median is _______.
What is the theoretical probability that a randomly chosen pinky length is more than 6.5 cm?
Explain the meaning of the 85
th percentile of this data.
Theoretical distribution
Using the theoretical distribution, complete the following statements. Use a normal approximation based on the sample mean and standard deviation.
IQR = _______
The 15
th percentile is _______.
The 85
th percentile is _______.
Median is _______.
What is the theoretical probability that a randomly chosen pinky length is more than 6.5 cm?
Explain the meaning of the 85
th percentile of this data.
Discussion questions
Do the data you collected give a close approximation to the theoretical distribution? In complete sentences and comparing the results in the sections titled
Describe the Data and
Theoretical Distribution , explain why or why not.
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
