A fitness course claims that it can improve an individual's physical ability. To test the effect of a physical fitness course on one's physical ability, the number of sit-ups that a person could do in one minute, both before and after the course, was recorded. Ten individuals are randomly selected to participate in the course. The results are displayed in the following table. Can it be concluded, from the data, that participation in the physical fitness course resulted in significant improvement?

Let d=(number of sit-ups that can be done after taking the course)−(number of sit-ups that can be done prior to taking the course)d=(number of sit-ups that can be done after taking the course)−(number of sit-ups that can be done prior to taking the course). Use a significance level of α=0.1α=0.1 for the test. Assume that the numbers of sit-ups are normally distributed for the population both before and after taking the fitness course.

Step 1 of 5: State the null and alternative hypotheses for the test.

Step 2 of 5:Find the value of the standard deviation of the paired differences. Round your answer to one decimal place.

Step 3 of 5:Compute the value of the test statistic. Round your answer to three decimal places

Step 4 of 5:Determine the decision rule for rejecting the null hypothesis H 0. Round the numerical portion of your answer to three decimal places.

Step 5 of 5: Make the decision for the hypothesis test. (accept or reject null)

An industrial organization has bought a specialized machine for $240,000 which will save $36,000 each year for 10 years. Straight Line (SL) basis depreciation should be taken into consideration with a depreciable life of 10 years. After tax MARR is 10% per year. Effective income tax rate is 40%. After 10 years, the machine will have zero salvage value. a) Draw a table showing Before Tax Cash Flow (BTCF) and After Tax Cash Flow (ATCF). b) Calculate the after tax PW and IRR. (Use interpolation method to find IRR). Is it feasible?

Please assume 2020 tax year:

12. Ms. Lincoln paid $14,340 of medical expenses this year that were not reimbursed by her insurance provider. Compute the after-tax cost of these expenses assuming that

1. Ms. Lincoln doesn’t itemize deductions on her Form 1040.

2. Ms. Lincoln itemizes deductions, her AGI is $64,400, and her marginal tax rate is 24 percent.

3. Ms. Lincoln itemizes deductions, her AGI is $209,200, and her marginal tax rate is 32 percent.

Coopy Corp. bought equipment for $500,000 on March 1, 2017 down paying $70,000 and signing a note for the rest. Coopy Corp. agreed to make 20 equal quarterly payments for 5 years starting June 1, 2017. The interest rate on this loan is 12%.

a) How much interst payable should be in Coopy Corp's balance on December 31, 2018?

b) What will be the carrying value (CV) on December 1, 2020 after the payment has been made?

7.   New Heights Aviation purchased on January 1, 2020 a plane for $ 500,000. The plane is expected to  

      have a 20 year life after which it can be sold for $ 100,000.

Required:

1. Compute depreciation expense for first three years using straight line.
2. Compute depreciation expense for the first three years using double-diminishing balance method.
3. At the end of three years the plane is sold for $400,000. Prepare journal entry to record the sale assuming depreciation was recorded using straight line.

Thread scheduling at the process level and at the kernel level. This topic requires more work on my part and I will give an updated draft. There may be more than one question here. Review the different allocation policies for kernel threads in relation to user threads – one to one, many to one, many to many, hybrid. These are sometimes referred to as an “M:N ratio” where M is the number of user threads and N is the number of kernel threads.

a) How is the choice between “process scope” (P) and“system scope” (S) related to these options? If “process scope” is chosen, where does the responsibility lie for scheduling threads?

b) How does Posix implement scheduling at the user thread level? If “system scope” (S) is chosen, does the programmer have any control over the scheduling of her threads?
