Many investors and financial analysts believe the Dow Jones Industrial Average (DJIA) gives a good barometer of the overall stock market. On January 31, 2006, 9 of the 30 stocks making up the DJIA increased in price (The Wall Street Journal, February 1, 2006). On the basis of this fact, a financial analyst claims we can assume that 30% of the stocks traded on the New York Stock Exchange (NYSE) went up the same day.

A sample of 79 stocks traded on the NYSE that day showed that 33 went up.

You are conducting a study to see if the proportion of stocks that went up is is significantly more than 0.3. You use a significance level of α=0.002.

What is the test statistic for this sample? (Report answer accurate to three decimal places.)
test statistic =

What is the p-value for this sample? (Report answer accurate to four decimal places.)
p-value =

The p-value is...

• less than (or equal to) αα
• greater than α

This test statistic leads to a decision to...

• reject the null
• accept the null
• do not reject the null

As such, the final conclusion is that...

• There is sufficient evidence to warrant rejection of the claim that the proportion of stocks that went up is more than 0.3.
• There is not sufficient evidence to warrant rejection of the claim that the proportion of stocks that went up is more than 0.3.
• There is evidence to support the claim that the proportion of stocks that went up is more than 0.3.
• There is not evidence to support the claim that the proportion of stocks that went up is is more than 0.3.

GBA 306 Statistical Methods of Business II – Case Study – Indiana Real Estate

Ann Perkins, a realtor in Brownsburg, Indiana, would like to use estimates from a multiple regression model to help prospective sellers determine a reasonable asking price for their homes. She believes that the following four factors influence the asking price (Price) of a house:
1)   The square footage of the house (SQFT)
2)   The number of bedrooms (Bed)
3)   The number of bathrooms (Bath)
4)   The lot size (LTSZ) in acres
She randomly collects online listings for 50 single-family homes. The data file is located in the Blackboard “Case Study Indiana Real Estate Data File Excel” within the Case Study folder.

Requirements and associated point values:
.
Part 2 – Estimate and interpret a multiple regression model where the asking price is the response variable and the other four factors are the explanatory variables.
The end result should be a Excel Regression Output

Dantley's Furniture manufactures rustic furniture. The cost accounting system estimates manufacturing costs to be $230 per table, consisting of 85% variable costs and 15% fixed costs. The company has surplus capacity available. It is Back​ Forrest's policy to add 55% markup to full costs. A large hotel chain is currently expanding and has decided to decorate all new hotels using the rustic style.​ Dantley's Furniture Incorporated is invited to submit a bid to the hotel chain. What is the lowest price per unit​ Dantley's Furniture should bid on this long- term order ?

Economics: Supply and Demand

USF issues parking permits to allow students to park on campus. The price of the permit is set by college administrators at their discretion, they do not consider market conditions. At the current price, some students complain that there aren’t enough spaces for them to park.

A) Describe this situation in economic terms and describe what this implies about the market equilibrium and the price of a parking permit.

B) Should the price of a parking permit be raised or lowered to fix this problem? Why? Explain.

C) Use the supply and demand model to describe how a graph of the market for parking permits would be affected by a change in price. You must include a graph and describe the graph.

A survey claims that the average cost of a hotel room in Atlanta is more than $125.50 per night. To test this claim, a researcher selects a random sample of 55 hotel rooms and finds that the mean cost per night is $130.75. The standard deviation of the population, σ, is known to be $2.50. At a = 0.05, is there enough evidence to support the claim?
