should be consider focusing on CAGE framework to study the Cultural, Administrative, Geographic and Economic differences with respect to the Germany country they want to invest in.

Cultural: - people`s language, values, behaviors and quality of life.

Administrative: - Rules and regulation related to the business in selected country.

Geographic Distance: - The size of the country, differences in climates, and nature of transportation and information networks. You can think of geographic distance as absolute, in terms of the miles or kilometers that separate a firm from another market or supplier.

Economic:- Income level, and the relative purchasing power and GDP of the country

1. Three different makes of cars were tested for fuel efficiency. For each make of car eighteen automobiles were randomly selected and subjected to standard driving procedures. Using the data from the following results compute the between treatments estimate of σ² and the within treatments estimate of σ². At the α=.05 level of significance, can the null hypothesis, that all fuel economies are the same, be rejected? Construct the ANOVA table for this data. (Use the formulas to compute the needed values by hand.) Ford Chevrolet Chrysler Miles Per Gallon 36 33 38 Standard Deviation 5 6 5.

Find the indicated probabilities using the geometric​ distribution, the Poisson​ distribution, or the binomial distribution. Then determine if the events are unusual. If​ convenient, use the appropriate probability table or technology to find the probabilities. A major hurricane is a hurricane with wind speeds of 111 miles per hour or greater. During the last​ century, the mean number of major hurricanes to strike a certain​ country's mainland per year was about 0.56. Find the probability that in a given year​ (a) exactly one major hurricane will strike the​ mainland, (b) at most one major hurricane will strike the​ mainland, and​ (c) more than one major hurricane will strike the mainland.

As part of an evaluation program, a sporting goods retailer wanted to compare the downhill coasting speeds of 4 brands of bicycles. She took 3 of each brand and determined their maximum downhill speeds. The results are presented in miles per hour in the table. Referring to the table, the null hypothesis that the mean downhill coasting speeds of the 4 brands of bicycles are equal will be rejected at a level of significance of 0.05 if the value of the test statistic is greater than ___________________.

Emerald Motors is an automobile dealer. The controller consults with you about the type of accounting used for a special offer to its new car customers. Emerald has offered to provide at no charge to the customer the first four recommended service visits (i.e., at 3,000, 6,000, 9,000, and 12,000 miles). It is a virtual certainty that all customers will exercise their rights to the service, and the cost of the services can be accurately estimated. The controller reasons that the estimated cost should be accrued when the sale of an automobile is made so that all of the costs of the sale can be matched with the revenue. How would you respond to the controller?

Mrs. Warrack, a retired archeologist, enjoys hiking in Badger Creed every other day. Usually she travels 3 miles per hike. During the past year Mrs. Warrack has recorded the times of her hikes. For a sample of 90 times, the mean was x ̅=23.18 minutes and the standard deviation was s = 1.87 minutes. Let μ mean the mean hiking time for the entire distribution of Mrs. Warrack’s 3-mile hike times (taken over the past year )    

How many degrees of freedom are there?    

Find a 0.95 confidence interval μ. Use t*= 1.987 .

A long segment of the suburban freeway is to be designed on level terrain. The level segment, however, is followed by a 4.5% grade, 2.0 miles in length. If the DDHV is 2,500 veh/h with 15% trucks (standard mix), how many lanes will be needed on the (a) upgrade, (b) downgrade, (c) level terrain segment to provide for the level of service C? Lane widths and lateral clearances may be assumed to be 12 ft and 6 ft, respectively. Ramp density is expected to be 1.0 ramps/mi. The PHF is 0.92. Good weather, no incidents, no work zones, and regular users of the facility may be assumed.

Create a C++ program that generates a random number from 1 to 100 using the rand() function. Give the user a total 5 chances to guess the number. Stop the program and indicate the user guessed the correct number and should be applauded. Also, please find out which guess was the closest to the actual number. For example, if the rand() produces 57 and the user guessed 10, 80, 52, 33 and 44 in their respective turns then print out the user didn’t guess the number and should a 1 mile for closest guess (57 – 52 = 5 miles).

Write a program that calculates mileage reimbursement for a salesperson at a rate of $0.35 per mile. Your program should interact (ask the user to enter the data) with the user in this manner:

MILEAGE REIMBURSEMENT CALCULATOR

Enter beginning odometer reading > 13505.2

Enter ending odometer reading > 13810.6

You traveled 305.4 miles. At $0.35 per mile, your reimbursement is $106.89.

** Extra credit 6 points: Format the answer (2 points), use JavaDoc (2 points), use constant for the rate per mile (2 points).
