A social psychologist is interested in how optimism is related to life satisfaction. A sample of individuals categorized as optimistic were asked about past, present, and projected future satisfaction with their lives. Higher scores on the life satisfaction measure indicate more satisfaction. Below are the data. What can the psychologist conclude with α = 0.05?

Compute the corresponding effect size(s) and indicate magnitude(s).
η² =

During mid-January 2004, average gas concentrations measured in Cache Valley were:

ammonium (NH4) = 16 µg/m^3

nitrate (NO3) = 45 µg/m^3

NH4 + NO3 = NH4NO3 (s)

a) Is NH4 or NO3 the limiting factor for the formation of NH4NO3? Explain using appropriate calculations.

b) Calculate the average NH4NO3 concentration (µg/m^3) based on these concentrations.

c) If we could reduce ammonium emissions by 15% by changing the composition of cattle feed, but nitrate remained the same, calculate the average NH4NO3 concentration (µg/m^3).

d) If we could reduce nitrate emissions by 15% through a vehicle inspection program, but ammonia remained the same, calculate the average NH4NO3 concentration (µg/m^3).

e) Based on your answers to part c) and d), which pollutant (NH4 or NO3) should we target first?

prepare general journal entries on Dec 31 to record the following unrelated year end adjustments.

a. On October 1, the company received 4 months rent in advance from a tenant whose rent is $650 per month. The $2,000 was credited to the Unearned Rent account.

b.) The prepaid insurance account has a $5,200 debit balance before adjustment. An examination of insurance policies shows $800 of unexpired insurance.

c.) The company collects rent revenue monthly from its tenants. One tenant whose rent is $825 per month has not paid his rent for November and December.

d.) The prepaid Insurance account has a $3,700 debit balance before adjustment. An examination of insurance policies shows $1,050 of insurance expired.

e.) Estimated depreciation on a copy machine for the office for the year is $1,500.

f.) The company has four office employees who each earn $150 per day for a five day work week that ends on Friday. The employees were paid on Friday, Dec 27, and have worked full days on Monday and Tuesday, December 30 and 31

Define lifetime customer value.

Explain the components used to calculate LCV.  

How may marketing managers use LCV in various strategies to grow marketing profits? Bullet points will be helpful.  

Your company, Lem Inc., is evaluating four different market segments. The company is going to select one segment as its primary segment for the next three years.   Using the excel program on lifetime value, what is the Total lifetime value of each of the following customer segments using a 5% discount rate. Show the value of each segment. If the company only has the resources to keep one segment, which segments should the company keep? Why? Include a table or graph showing a comparison of each segment. Your written explanation will be one page or less.  

Segment A has a 90% satisfaction rate, the sales force spends $200 each year calling on them, with an average margin of 50% on a sales of $1000. The marketing department has an integrated marketing communication strategy that costs $300 to attract new customers. There are 1000 of these clients in this segment.

Segment B has a 95% satisfaction rate, the sales force spends $400 each year calling on them, with an average margin of 40% on a sales of $1000. The marketing department has an integrated marketing communication strategy that costs $900 to attract new customers. There are 500 of these clients in this segment.

Segment C has a 65% satisfaction rate, the sales force spends $25 each year calling on them, with an average margin of 80% on a sales of $1000. The marketing department has an integrated marketing communication strategy that costs $30 to attract new customers. There are 3000 of these clients in this segment.

Segment D has a 80% satisfaction rate, the sales force spends $200 each year calling on them, with an average margin of 60% on a sales of $1000. The marketing department has an integrated marketing communication strategy that costs $300 to attract new customers. There are1500 of these clients in this segment.

The following case applies to questions 1-3:

Clients can choose between three diets at a weight-loss treatment center. An experiment was performed to determine if there is a difference between the diets. Fifteen patients were randomly selected and divided evenly into three groups of five for each diet. After 30 days the weight change (in pounds) for each client was recorded as shown below.

Diet A: 4, 4, 5, 5, 7

Diet B: 5, 6, 6, 7, 7

Diet C: 7 ,8, 8, 9, 9

What is the alternative hypothesis?

1. None of the diet variances are equal
2. At least one of the diet means is not equal
3. All of the diet means are equal
4. All of the diet variances are equal
5. None of the diet means are equal

What is the critical value at the 0.05 level of significance?

1. 3.89
2. 19.4
3. 6.93
4. 3.29

What is the test statistics and does the experiment conclude that there is a difference in mean weight loss among the three diets at the 0.05 level of significance?

1. 2.25 and yes there is a difference in diet
2. 13.47 and no there is not a difference in diet
3. 13.47 and yes there is a difference in diet
4. 2.25 and no there is no difference in diet

Consider a 12 months two-security potential investment from the following three. The correlation coefficients between pairs of the stocks are as follows: Corr(A,B) = 0.85, Corr(A,C) = 0.60, Corr(A,D) = 0.45. Each stock has an expected return of 8% and a standard deviation of 20%.

Your entire portfolio is now composed of stock A and you can add some of only one stock to your portfolio.

Required:

1. Identify the stock to be added to Stock A and determine the optimum portfolio mix.                                                                                                                       [8 Marks]

2. If the overall rate of return on the LUSE is 9%, the risk-free rate is 4%, and the beta of 1.2, is it justifiable to invest in the new portfolio?             [5 Marks]

3. Discuss the assumption of keeping the correlations between stock returns constant in modern portfolio theory.                                                        [7 Marks]

Suppose three competing airlines each schedule their own flight to Waco which arrives there between 2:00 and 3:00 pm according to a continuous uniform distribution. All three flights are mutually independent.

(a) If Ralph shows up at the airport at 2:00 and decides he will watch all three arrivals, what is the expected time that he observes the third and last arrival?

(b) If each airline’s flight only stays on the ground for 10 minutes, find or estimate the probability that all 3 airlines will have a plane on the ground at Waco at some point in the hour from 2:00 to 3:00.
