BUSN 340 Business Statistics

Major Project Assignment

1.) Refer to the real estate data in Blackboard, which reports information on homes

sold in the Phoenix, Arizona, area during the last year. Organize the data by the

number of bedrooms into a frequency distribution.

A.) What is the typical number (average) of bedrooms?

B.) What are the fewest (minimum) and the most (maximum) number of

bedrooms offered in the market?

2.) Sort the real estate data into a table that shows the number of homes that have a

garage attached versus those that do not have a garage in each of the five townships.

If a home is selected at random, compute the following probabilities.

A.) The home has a garage attached.

B.) Given that it is in Township 5, that it does not have a garage attached.

C.) The home has a garage attached and is in Township 3.

3.) Refer to the real estate data and develop the following confidence intervals using

statistical software. (Minitab: Stat ? Basic Statistics ? Graphical Summary ? Select

variable, then enter a 95% Confidence Interval).

A.) Develop a 95 percent confidence interval for the mean selling price of the

homes.

B.) Develop a 95 percent confidence interval for the mean distance the home

is from the center of the city.

4.) Refer to the baseball data in Blackboard, which reports information on 30 major

league teams for the 2008 baseball season. Select the variable that refers to the

seating capacity (size) of the stadium. Find the mean, median, mode and the

standard deviation.

5.) Refer to the baseball data in Blackboard. Assume the seating capacity (size)

represents the population. Develop a histogram of the data. Would it seem

reasonable from this histogram to conclude that the seating capacity population

follows the normal distribution? 1 6.) Refer to the wage data, which report information on annual wages for a sample

of 100 workers. Also included are variables relating to industry, years of education,

and gender for each worker. (Minitab: Graph ? Box plot ? One y Simple ? select

variable)

A.) Develop a box plot for the variable annual wage. Are there any outliers?

Briefly explain your findings.

B.) Develop a box plot for the variable years of education. Are there any

outliers? Briefly explain your findings. 2
