Your company assembles five different models of a motor scooter that is sold in specialty stores in the United States. The company uses the same engine for all five models. You have been given the assignment of choosing a supplier for these engines for the coming year. Due to the size of your warehouse and other administrative restrictions, you must order the engines in lot sizes of 1,240 units. Because of the unique characteristics of the engine, special tooling is needed during the manufacturing process for which you agree to reimburse the supplier. Your assistant has obtained quotes from two reliable engine suppliers and you need to decide which to use. The following data have been collected:

Note: Assume that half of lot size is in inventory on average (1,240/2 = 620 units).

Two qualified suppliers have submitted the following quotations:

Your assistant has obtained the following freight rates from your carrier:

Note: Per ton-mile = 2,000 lbs. per mile.

a-1. Calculate the total cost for each supplier. (Round your answers to the nearest whole number.)

a-2. Which supplier would you select?

b-1. If you could move the lot size up to ship in truckload quantities, calculate the total cost for each supplier. (Do not round intermediate calculations. Round "Required lot size for truckload" and final answers to the nearest whole number.)

HINT: Use (full) truckload cost rates and the lowest (feasible) unit cost for all calculations. For example, if there are 8.3 orders per year, don’t split the 8.3 orders into 8 full truckloads and 0.3 less-than-truckloads - use the full truckload rate for all 8.3 orders. For annual purchase cost, don’t use two different unit costs for the 8 complete orders and the 0.3 partial orders – use the lowest (feasible) unit cost for all 8.3 purchase orders based on the lot size needed for a full truckload.

b-2. Would your supplier selection change?

On a drive of 800 miles how much CO₂ do you release in to the atmosphere in kilograms. Assume your car consumes 24 miles to the gallon.(Your gas is 100% octane, and has a mass of 2.9 kg/US gallon)

An investigator compares the durability of two different compounds used in the manufacture of a certain automobile brake lining. A sample of 65 brakes using Compound 1 yields an average brake life of 37,409 miles. A sample of 31 brakes using Compound 2 yields an average brake life of 49,036 miles. Assume the standard deviation of brake life is known to be 1341 miles for brakes made with Compound 1 and 2961 miles for brakes made with Compound 2.  Determine the 95% confidence interval for the true difference between average lifetimes for brakes using Compound 1 and brakes using Compound 2.

Step 1 of 2: Find the critical value that should be used in constructing the confidence interval.

Step 2 of 2: Construct the 95% confidence interval. Round your answers to the nearest whole number.

Please provide formulas for each entry with explanations. Thank you.

Prepare a depreciation schedule showing depr. exp., accumulated depreciation and ending book value, year-by-year.

Suppose that a sample of 36 brand X tires has a sample mean life of 54000 miles and a sample standard deviation of 6000 miles, while a sample of 36 brand Y tires produces a sample mean of 60000 miles and a sample standard deviation of 9000 miles.

3. The company manufacturing the brand Y tires claims that their tires last longer than the brand X tires, on average. Is there enough evidence, at significance level ? = 0.05, to support the company’s claim? Also, give a range for the p-value of the test.

4. The company manufacturing the brand X tires claims that their manufacturing process yields more consistently performing tires (lower variance of the lifespan) than the brand Y tires. Is there enough evidence, at significance level ? = 0.05, to support the company’s claim?

Speedy delivery company on Jan. 1 2021, purchased a van for $20,000. to complete the purchase, the company also incurred $800 shipping cost and $1,200 sales tax.

Speedy estimates that at the end of its the four- year service life the van will be worth 4,000. during the four year period, the company expects to drive the van 100,000 miles. actual miles driven each year were 32,000 miles in year 1; 35,000 in year 2 and 27,000 in year 3 and 6,000 miles in year 4.

A. using straight depreciation method, what is annual depreciation expense?

B. Using the double declining balance method what are the amounts of depreciation expense for year 3 and year 4?

C. using activity-based method what is the balance of accumulated depreciation at the end of year 2?  

PROGRAM IN C++

The distance a vehicle travels can be calculated using the following equation: distance = speed * time

For example, if a train travels 40 miles per hour for 3 hours, the distance traveled is 120 miles. Write a program that asks the user for the speed of a vehicle (in miles per hour) and how many hours it has traveled. The program should then use a loop to display the distance the vehicle has traveled for each hour of that time.

Sample Output: What is the speed of the vehicle in mph? 40 For how many hours has it traveled? 3 Hour Distance Traveled in Miles

----------------------------------

1 40

2 80

3 120

Input Validation:

Do not accept a negative number for speed and do not accept any value less than 1 for time traveled. Try to validate using loops.

1 point) It is necessary for an automobile producer to estimate the number of miles per gallon achieved by its cars. Suppose that the sample mean for a random sample of 100100 cars is 28.228.2 miles and assume the standard deviation is 3.23.2 miles. Now suppose the car producer wants to test the hypothesis that μμ, the mean number of miles per gallon, is 29.829.8 against the alternative hypothesis that it is not 29.829.8. Conduct a test using α=.05α=.05 by giving the following:

(a)    positive critical zz score    

(b)    negative critical zz score    

(c)    test statistic    

The final conclustion is

A. We can reject the null hypothesis that μ=29.8μ=29.8 and accept that μ≠29.8μ≠29.8.
B. There is not sufficient evidence to reject the null hypothesis that μ=29.8μ=29.8.

Nike claims that the number of miles a jogger can get a on a pair of Nike’s running shoes is higher than 1000. Moreover, Nike also claims that their shoes outperform Adidas shoes by more than 15 miles. We have samples of 150 joggers using Nike shoes and 170 using Adidas shoes. The sample average of miles they got are 1015 for Nike and 995 for Adidas. The sample standard deviations are 100 for Nike and 50 for Adidas.

a.) At a 5% level of significance, is there statistical evidence showing that Nike shoes get more than 1000 miles?

b.) Obtain the p-value for the previous test. What does it mean?

c.) At a 5% level of significance, is there statistical evidence showing that Nike shoes outperform Adidas shoes?

d.) Obtain the p-value for the previous test. Interpret.
