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 pinkie finger (in cm.)
Randomly survey 30 adults. Round to the nearest 0.5 cm.

Construct a histogram. Make 5-6 intervals. Sketch the graph using a ruler and pencil. Scale the axes.
Calculate the Following
$\overline{x}=$
$s=$
Draw a smooth curve through the top of the bars of the histogram. Use 1-2 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, etc.?)
Analyze the distribution
Using your sample mean, sample standard deviation, and histogram to help, what was the approximate theoretical distribution of the data from the section titled "Collect the Data"?
$X$ ~
How does the histogram help you arrive at the approximate distribution?
Describe the data
Using the data in the section titled "Collect the Data" complete the following statements. (Hint: order the data)
$(\mathrm{IQR}=Q3-Q1)$
IQR =
15th percentile is:
85th percentile is:
Median is:
What is the empirical probability that a randomly chosen pinkie length is more than 6.5 cm?
Explain the meaning the 85th percentile of this data.
Theoretical distribution
Using the Theoretical Distribution in the section titled "Analyze the Distribution"
IQR =
15th percentile is:
85th percentile is:
Median is:
What is the theoretical probability that a randomly chosen pinkie length is more than 6.5 cm?
Explain the meaning of the 85th percentile of this data.
Discussion questions
Do the data from the section entitled "Collect the Data" give a close approximation to the theoretical distribution in "Analyze the Distribution."In complete sentences and comparing the results in the sections titled "Describe the Data" and "Theoretical Distribution", explain why or why not.
Questions & Answers
Is there any normative that regulates the use of silver nanoparticles?
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
Tarell
what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.
Tarell
what is the Synthesis, properties,and applications of carbon nano chemistry
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.

Do you know which machine is used to that process?
Privacy Information Security Software Version 1.1a

1 It is estimated that 30% of all drivers have some kind of medical aid in South Africa. What is the probability that in a sample of 10 drivers: 3.1.1 Exactly 4 will have a medical aid. (8) 3.1.2 At least 2 will have a medical aid. (8) 3.1.3 More than 9 will have a medical aid.
