Project 3
Project 3 instructions
Based on Brase&Brase: sections 6.1-6.3
Note that you must do this project on your own—you may not work
with other students. You are always welcome to ask your instructor for help.
Visit theNASDAQ historical prices weblink. First, set the date range to be for exactly 1 year ending
on the Monday that this course started. For example, if the current term
started on April 1, 2018, then use April 1, 2017 – March 31, 2018. (Do NOT use
these dates. Use the dates that match up with the current term.) Do this by
clicking on the blue dates after “Time Period”. Next, click the “Apply” button.
Next, click the link on the right side of the page that says “Download Data”to
save the file to your computer.
This project will only use the Closevalues. Assume that the
closing prices of the stock form a normally distributed data set. This means
that you need to use Excel to find the mean and standard deviation.Then, use
those numbers and the methods you learned in sections 6.1-6.3 of the course
textbook for normal distributions to answer the questions. Do NOT count the number of data points.
Complete this portion of the assignment within a single Excel
file. Show your work or explain how you obtained each of your answers. Answers
with no work and no explanation will receive no credit.
1. a) Submit
a copy of your dataset along with a file that contains your answers to all of
the following questions.
b) What the mean and
Standard Deviation (SD) of the Close column in your dataset?
c) If a person bought
1 share of Google stock within the last year, what is the probability that the
stock on that day closed at less than the mean for that year? Hint: You do not
want to calculate the mean to answer this one. The probability would be the
same for any normal distribution. (5
points)
2. If a
person bought 1 share of Google stock within the last year, what is the
probability that the stock on that day closed at more than $950?(5 points)
3.
If a person bought 1 share of Google stock within the last year,
what is the probability that the stock on that day closed within $50 of the
mean for that year? (between 50 below and 50 above the mean)(5 points)
4.
If a person bought 1 share of Google stock within the last year,
what is the probability that the stock on that day closed at less than $800 per
share.Would this be considered unusal? Use the definition of unusual from the
course textbook that is measured as a number of standard deviations(5 points)
5.
At what prices would Google have to close in order for it to be
considered statistically unusual? You willhave a low and high value.Use the
definition of unusual from the course textbook that is measured as a number of
standard deviations.(5 points)
6.
What are Quartile 1, Quartile 2, and Quartile 3 in this data set?
Use Excel to find these values. This is the only question that you must answer
without using anything about the normal distribution.(5 points)
7.
Is the normality assumption that was made at the beginning valid?
Why or why not? Hint: Does this distribution have the properties of a normal
distribution as described in the course textbook? Real data sets are never
perfect, however, it should be close. One option would be to construct a
histogram like you did in Project 1to see if it has the right shape.Something
in the range of 10 to 12 classes is a good number.(5 points)
There are also 5 points for miscellaneous items like
correct date range, correct mean, correct SD, etc.
