EACH ONE IS ITS OWN ASSIGNMENT AND SHOULD NOT BE MIXED TOGETHER THERE ARE THREE DIFFERENT ASSIGNMENTS! I ALSO PROVIDED THE PAGES OUT OF THE BOOK THAT NEED TO BE USED.

WEEK 1 TECHNOLOGY ASSIGNMENT

Collecting data and creating graphs – Collect data from 30 people from your work, school, neighborhood, family, or other group.  Ask a quantitative question, such as, “How many pets do you have?”  or  “How many college classes have you taken?”   Explain your population, sample, and sampling method and what level of measurement your data is (nominal, ordinal, interval, or ratio).  Use technology (StatCrunch, Statdisk, or Excel) to create a Histogram of your data and explain the shape of the distribution (bell-shaped, uniform, right-skewed, or left-skewed) and possible reasons why the distribution is this shape.  Explain the importance of this data, what you find interesting about the data, and why the public should know. Look up a newspaper, e-pub, or journal article that confirms or denies the results of your small study.

Provide the your graph as an image

SAVE THIS DATA TO BE USED IN FUTURE WEEK’S TECHNOLOGY ASSIGNMENTS!

WEEK 2 TECHNOLOGY ASSIGNMENT

Generating Summary Statistics – Using the data you collected last week, use technology (StatCrunch, Statdisk, or Excel) to find the mean, median, mode, standard deviation, and five number summary.  Explain how these statistics describe your data and what they suggest about your sample.  Create a boxplot of the data and identify any outliers in your data by using the methods on page 121 of your textbook and discuss how those outliers are affecting your results.

Provide your graph as an image to submit.

WEEK 3 TECHNOLOGY ASSIGNMENT

Calculating Binomial Probabilities – Suppose you work for an airline and you are taking reservations for a flight on an aircraft that has 152 seats.  You know, based on historical flights trends, that if you sell a single ticket there is a 91% chance that the person with the ticket will actually show up for the flight.  You decide to try to make a little extra money by overbooking your flight and you sell 160 tickets hoping that not more than 152 people will actually show up for the flight (note: this is a common business practice!  Click here to watch a video that explains why)

Explain how this scenario meets the four requirements in the definition of a Binomial Distribution (page 200)

PAGE 200:

Identify what n and p are in this example

Use technology (StatCrunch, Statdisk, or Excel) to calculate the probability that if you sell 160 tickets for your flight, more passengers will show up than there are seats available (again, the plane has 152 seats total).  Post an image of your technology output using the Insert/Edit Image feature in Blackboard (no attachments!)

Based on this probability, do you think it is a wise business practice to oversell your flight in this manner?   Explain.
