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.

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.

Universe Studios Sentiasa is a theme park licensed from a major
Bollywood studio. Customers pay a fixed fee to enter the park where
they can participate in a variety of activities such as riding
roller-coasters, playing on slides and purchasing themed souvenirs
from gift shops.
Customers purchase tickets to enter the theme park from ticket
offices located outside the park. Tickets are only valid on the day
of purchase. Adults and children are chargedthe same price for
admission to the park. Tickets are preprinted and stored in each
ticket office. Tickets are purchased using either cash or credit
cards. Each ticket has a number comprising of two elements - two
digits relating to the ticket office followed by six digits to
identify the ticket. The last six digits are in ascending
sequential order.All cash ticket sales are recorded on a computer
showing the amount of each sale and the number of tickets issued.
This information is transferred electronically to the accounts
office. Cash is collected regularly from each ticket office by two
security guards. The cash is then counted by two accounts clerks
and banked on a daily basis. The total cash from each ticket office
is agreed to the sales information that has been transferred from
each office. Total cash received is then recorded in the cash book,
and then the general ledger.
The park also accepts Visa and Mastercard. Payments by credit cards
are authorised online as the customers purchase their tickets.
Computers in each ticket office record the sales information, which
is transferred electronically to the accounts office. Credit card
sales are recorded for each credit card company in a receivables
ledger. When payment is received from the credit card companies,
the accounts clerks agree the total sales values to the amounts
received from the credit card companies, less the commission
payable to those companies. The receivables ledger is updated with
the payments received. You are now commencing the planning of the
annual audit of Universe Studios Sentiasa .
Required
(a) Identify four (4) risks that could affect the assertion of
completeness of sales and cash receipts. [12 marks] (b) Discuss the
extent to which substantive procedures could be used to confirm the
assertion of completeness of income in Universe Studios Sentiasa.
[6 marks] (c) Provide any four (4) substantive analytical
procedures that can be used to give assurance on the total income
from ticket sales for one day in Universe Studios Sentiasa. [12
