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?

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.

  1. Risk Likelihood (3 pts.)

A product improvement project involves an existing product (M), with minor complexity (C), and is dependent for schedule on an existing system (D).   (reference Risk Assessment Calculations document, Likelihood table).  

Consider that criteria are weighted as follows:

M is (0.5), C is (0.3), D is (0.2)

Calculate the Composite Likelihood Factor (CLF).

W1= 0.5, W2=0.3, W3=0.2

(CLF) = W1 * M + W2 * C + W3 * D = 0.5 * 0.1 + 0.3 * 0.3 + 0.2 * 0.3 = 0.05 + 0.09 + 0.06 = 0.20

  1. Risk Impact (3 pts.)

A product test failure is expected to have a minor impact on overall technical performance and be correctable within 2 months at a cost of 10 percent. (reference Risk Assessment Calculations document, Impact table).  

Consider that criteria are weighted as follows:

TI is Moderate (0.5), CI is Minor (0.3), SI is Low (0.2)

Calculate the Composite Impact Factor (CIF).

  1. Risk Consequence Rating (1 pt.)

Using the previous problems #1 Risk Likelihood (CLF) and #2 Risk Impact (CIF), calculate the Risk Consequence Rating (RCR).

A6 – Shipping Calculator

Assignment

Introduction

In this part, you will solve a problem described in English. Although you may discuss ideas with your classmates, etc., everyone must write and submit their own version of the program. Do NOT use anyone else’s code, as this will result in a zero for you and the other person!

Shipping Calculator

Speedy Shipping Company will ship your package based on the weight and how far you are sending the package, which can be anywhere in the world. They will only ship small packages up to 10 pounds. You need to have a program, which will help you determine how much they will charge.

The charges are based on each 500 miles shipped. The mileage should be in whole numbers. They are not prorated, i.e., 600 miles is the same charge as 900 miles; in other words, 600 and 900 miles is counted as 2 segments of 500 miles each.

Here is the table they gave you:

Package Weight Rate per 500 miles shipped

Charge

2 pounds or less

$1.50

More than 2 but not more than 6

$3.70

More than 6 but not more than 10

$5.25

Your code needs to validate the input completely, e.g., the weight and mile amounts must be positive. If an input is invalid, e.g., the weight is zero or less, you should display an appropriate, professional error message, e.g., Error: Weight must be greater than zero!, which should be offset and surrounded by white space, so it stands out, and repeat getting that input until valid input is received. Keep in mind, the user will find it annoying if they must enter both the miles and weight at the same time, and only one of them caused an error, or they must reenter already valid data. Also, make sure you follow the Code Conventions and good programming practices, e.g., appropriately initialize variables to zeros, avoid stacked if or if-else constructs unless necessary, don’t use break or continue to get out of a loop, goto, etc.; in other words, you should NOT use stacked if/if-else constructs, break, or continue for this assignment.

At this point for the code, you should only solve the problem using what you learned from modules 1 – 6, i.e., NO arrays, functions other than main(), etc. Only if all the input is valid, should the program calculate and display one shipping charge, and pause, but not quit, before proceeding to a new customer. Your test cases should test the various possibilities, and the limits of the program, which means, you will need to use an appropriate loop, which will ask if you would like to process the next customer or not by asking them to enter an appropriate value. Once there are no more customers to process, the program should display Good-bye! and end. Remember to solve each aspect of the program separately, and then, put the parts together.

Hints: You may need to reset any values after you display the answer and before you get the input for the next customer. Big Helpful Hint: For the number of segments calculation, you may want to start with integer division, e.g., 1200 miles / 500 miles per segment = 2 segments, and then, expand on that.

You should be able to solve this problem with only one loop.

Three different companies each purchased trucks on January 1, 2018, for $50,000. Each truck was expected to last four years or 200,000 miles. Salvage value was estimated to be $5,000. All three trucks were driven 66,000 miles in 2018, 42,000 miles in 2019, 40,000 miles in 2020, and 60,000 miles in 2021. Each of the three companies earned $40,000 of cash revenue during each of the four years. Company A uses straight-line depreciation, company B uses double-declining-balance depreciation, and company C uses units-of-production depreciation.
