A construction crane collapsed while working on a new building for Metro City. A pedestrian was killed. The husband of the victim is suing Metro City and the construction company. The city attorney, in consultation the city’s liability insurer and the construction company, has offered two out-of-court settlements to the husband of the victim. Here are the settlement options

Option 1: Four annual payments of $225,000 with the first payment one year from today.

Option 2: Five Payments of $200,000 with the payments one year, three years, five years, seven years, and nine years from today.

Assuming a 6% discount rate, which settlement option is the best from the perspective of Metro City?

We interviewed two groups of 50 college students respectively from UIC and DePaul to know if they rather watch NFL Football vs. some other sport on Sunday.

Actual Data

Based on the statistics above, we need to determine if there is a relationship between the university of a student and watching Football. Answer to the following questions to arrive at the conclusion.

• What are Ho and Ha?
• What are the chi-square values?
• What is the degrees of freedom?
• What is the p-value?
• For alpha=0.05, what would be our statistical conclusion?
• Write out the full conclusion in English

2. Weight of Car: Miles gallon – Do heavier cars really use more gasoline? The following data were obtained from Consumer Reports (Vol 62 no. 4). Weight of car is in hundreds of pounds.

Car Weight 27 44 32 47 23 40 34 52
MPG 30 19 24 13 29 17 21 14

A simple linear regression of the model MPG = b0 + b1 WEIGHT
The results are shown below:

MPG & CAR WEIGHT
REGRESSION FUNCTION & ANOVA FOR MPG

MPG = 43.32625 - 0.600702 WEIGHT

R-Squared = 0.895426
Adjusted R-Squared = 0.877997

Questions:

1. What sort of relationship exists between MPG and car weight?

2. Does the relationship make sense to you? Why or why not?

3. Test the hypotheses H0: b1 = 0 against H A: b1 ?0 a level of significance ? = 0.01. What is your conclusion?

MODEL: MPG= b0 + b1 WEIGHT

H0: b1 = 0

H A: b1 ? 0

Consider two portfolios. One portfolio consists of a $10,000 investment in AAPL, and the other also consists of a $10,000 investment in AAPL, but with 50% leverage ($5,000 of the investor's capital, $5,000 borrowed). Now consider two separate moves in the value of AAPL; a 10% upside return and a 10% downside return. Explain the effect of leverage on the volatility and return by comparing the performance of each portfolio.

Seasonal affective disorder (SAD) is a type of depression during seasons with less daylight (e.g., winter months). One therapy for SAD is phototherapy, which is increased exposure to light used to improve mood. A researcher tests this therapy by exposing a sample of patients with SAD to different intensities of light (low, medium, high) in a light box, either in the morning or at night (these are the times thought to be most effective for light therapy). All participants rated their mood following this therapy on a scale from 1 (poor mood) to 9 (improved mood). The hypothetical results are given in the following table. Light Intensity Low Medium High Time of Day Morning 5 5 7 6 6 8 4 4 6 7 7 9 4 9 5 6 8 7 Night 5 6 9 8 8 7 6 7 6 7 5 8 4 9 7 3 8 6 (a) Complete the F-table and make a decision to retain or reject the null hypothesis for each hypothesis test.
