To study the effect of curing temperature on shear strength of a certain rubber compound, 80 specimens were cured at 150°C and 105 were cured at 130°C. The specimens cured at 150°C had an average shear strength of 620 psi, with a standard deviation of 20 psi. Those cured at 130°C had an average shear strength of 750 psi, with a standard deviation of 30 psi. Let μXμX represent the population mean strength for the specimens cured at 130°C and let μYμY represent the population mean strength for the specimens cured at 150°C. Find a 95% confidence interval for the difference μX−μYμX−μY . Round the answers to two decimal places.

For this program, remember to use feet and inches. First, ask the user for the name of students they have in their class. Then, using a loop, you will ask for each student’s height. However, you will have to use two separate variables, one for feet and one for inches. Then, you will have to call two functions. The first function will check if the values entered are valid (check if number of feet is positive, check if number of inches is positive and check if number of inches is not higher than 12). If one of these conditions is not met, print an informative message and run this command right after exit(0); (you will have to include at the top of your program). This command will terminate your program. The second function will check if the user is in the “height range”; if the user is between 5’ 8” and 7’ 7”, the student has higher chances of being recruited by a basketball team; otherwise, not so much. Whichever the case is, print an informative message. You can make your functions work whichever way you prefer, but the “checking” must be done inside them. Also, you must use function prototyping.

I'm trying to do some pratice problems in the book and here is one of them.

Write a method cleanCorruptData that accepts an ArrayList of integers and removes any adjacent pair of integers in the list if the left element of the pair is smaller than the right element of the pair. Every pair's left element is an even-numbered index in the list, and every pair's right element is an odd index in the list. For example, suppose a variable called list stores the following element values: [3, 7, 5, 5, 8, 5, 6, 3, 4, 7]

We can think of this list as a sequence of pairs: (3, 7), (5, 5), (8, 5), (6, 3), (4, 7). The pairs (3, 7) and (4, 7) are "bad" because the left element is smaller than the right one, so these pairs should be cleaned (or removed). So the call of cleanCorruptData(list); would change the list to store the following element values: [5, 5, 8, 5, 6, 3]

If the list has an odd length, the last element is not part of a pair and is also considered "corrupt;" it should therefore be cleaned by your method. If an empty list is passed in, the list should still be empty at the end of the call. You may assume that the list passed is not null. You may not use any other arrays, lists, or other data structures to help you solve this problem.

Pepper’s Products manufactures and sells two types of chew toys for pets—Squeaky and Silent. In May, Pepper’s Products had the following costs and revenues.

Pepper’s Products currently uses labor costs to allocate all overhead but is considering implementing an activity-based costing system. After interviewing the sales and production staff, management decides to allocate administrative costs on the basis of direct labor costs but to use the following bases to allocate the remaining overhead.

Required:

a. Complete the income statement using the preceding activity bases.

c. Restate the income statement for Pepper's Products using direct labor costs as the only overhead allocation base.

Deutsche Schnitzel, a producer of high quality German baked goods, adopted IFRS in 2005 with the rest of the European Union. Two years ago, DS replaced all of its machinery and decided to record it at fair value rather than historical cost. The purchase price of the machinery (in U.S. dollars) was $1,100,000. In addition, DS spent $75,000 in shipping and installation. Trial runs, including labor, materials, and applicable overhead, came to $50,000. DS assumes that the interest expense from their current loans for the new machinery was $25,000. Assume that DS uses straight line depreciation. The machinery has a 6 year useful life and a salvage value of $225,000. DS records a full year of depreciation in the year of purchase, regardless of when the purchased the asset.

a. Assuming that DS paid cash for the all costs associated with the purchase of the equipment, make the journal entry to record the historical cost of the new machinery.

b. At the end of that first year, the fair value of the machinery was $975,000. Ignoring taxes, make any necessary journal entries for the first year.

c. At the end of the next year, the fair value of the machinery was $900,000. Ignoring taxes, make any necessary journal entries for the second year.

Silvah Leasing Ltd. (SLL) is a private company founded over 20 years ago. Its main business is providing lease financing to small to medium-size local businesses for financing their operating equipment, store fixtures, and so on.

SLL’s business is direct lease financing, and the company never takes ownership of any of the leased assets. Leasing is popular with smaller businesses since the economy has been in a recession, and leasing assets rather than buying conserves cash. Many larger financial institutions have become more active in selling leases to the smaller customers that have been

SSL’s main source of business, to increase their own revenues during the recessionary times. Equipment vendors are also increasingly providing financing with equipment sales to increase their own business.

D. Silvah owns the majority of the common shares and runs the business with three employees. There are two minority shareholders who are family members, M. Silvah and J. Silvah. Your firm has audited SLL for several years. The company’s bank demands annual audited financial statements because of SLL’s large outstanding bank loan.
