Course Project #1 Overview
 The Course Project consists of 10 Requirements for you to complete. The Course Project is due at the end of  Week 6. See the Syllabus section ”Due Dates for Assignments & Exams” for due date information. All of the information you need to complete the Course Project is located in this Workbook. 

• There are eight worksheets in the workbook you will need to complete.

• A list of October transactions

• A Chart of Accounts reference sheet

• A Grading Rubric to help explain what is expected.

• Each worksheet has the Check Figures embedded as a comment.

Scenario
 You’ve just secured a new client in your accounting practice, the Rawls Repair Corporation (RRC), a brand new small business specializing in bicycle repair. The owner, Rob Rawls, is a terrific cyclist and bike repair specialist, but definitely not an accountant. Your job is to help Rob put his affairs in order. Luckily Rob has only been in operation for a month and things have not gotten too out of hand yet! Rob has to submit his financial statements to his investors and doesn’t know where to begin. It’s your job to go through the complete Accounting cycle to prepare the financial statements for the RRC.

Guidelines
 Use the embedded assistance in the template, guidance in your textbook, and examples in the weekly lectures to complete this project.  Should you have any questions contact your professor.
During its first month of operation, the Rawls Repair Corporation, which specializes in bicycle repairs, completed the following transactions.
Use the following account descriptions for journal entries.




REQUIREMENT #1: Prepare journal entries to record the October transactions in the General Journal below. Remember that Debits must equal Credits—All of your Journal Entries should balance.
REQUIREMENT #2: Post the October journal entries to the following T-Accounts and compute ending balances.

REQUIREMENT #3: Prepare a trial balance for October in the space below.
Requirement #4: Prepare adjusting entries using the following information in the General Journal below. Show your calculations!   

a) One month's insurance has expired.     

b) The remaining inventory of repair supplies is $194.   

c) The estimated depreciation on repair equipment is $70.      

d) The estimated income taxes are $40.  
Requirement #5: Post the adjusting entries on October 31 below to the General Ledger T-accounts and compute adjusted balances. Just add to the balances that are already listed.
REQUIREMENT #6: Prepare an Adjusted Trial Balance in the space below.
Requirement #7: Prepare the financial statements for Rawls Repair Corporation as of October 31 in the space below.      

You will only be preparing the Income Statement, Statement of Retained Earning, and the Balance Sheet.      

The Statement of Cash Flows is a required Financial Statement, but is not required for this project.
Requirement #8: Prepare the closing entries at October 31 in the General Journal below. Hint:Use the balances for each account which appear on the Adjusted    

Trial Balance for your closing entries.    
Requirement #9: Post the closing entries to the T-Accounts on the General Ledger worksheet and compute ending balances. Just add to the adjusted balances already listed.  
Requirement #10: Prepare a post-closing trial balance as of October 31 in the space below.

You are not required to submit this assignment to Turnitin 9.3 If you use a 0.10 level of significance in a two tail hypothesis test, what is your decision rule for rejecting a
null hypothesis that the population mean is 500 if you use the Z test?

9.13 Do students at your school study more than, less
than, or about the same as students at other business schools? BusinessWeek reported that at the top 50 business schools, students studied an average of 14.6 hours per week. (Data extracted from “Cracking the Books,” Special Report/Online Extra, www.businessweek.com, March 19, 2007.) Set up a hypothesis test to try to prove that the mean number of hours studied at your school is different
from the 14.6 hour per week benchmark reported by Business Week.
a. State the null and alternative hypotheses.
b. What is a Type I error for your test?
c. What is a Type II error for your test?

9.14 The quality-control manager at a light bulb factory needs to determine whether the mean life of a large shipment of light bulbs is equal to 375 hours. The population standard deviation is 100 hours. A random sample of 64 light bulbs indicates a sample mean life of 350 hours.
a. At the 0.05 level of significance, is there evidence that the mean life is different from 375 hours?
b. Compute the p-value and interpret its meaning.
c. Construct a 95% confidence interval estimate of the population mean life of the light bulbs.
d. Compare the results of (a) and (c). What conclusions do you reach?

9.25 A manufacturer of chocolate candies uses machines to package candies as they move along a filling line. Although the packages are labeled as 8 ounces, the company wants the packages to contain a mean of 8.17 ounces so that virtually none of the packages contain less than 8 ounces. A sample of 50 packages is selected periodically, and the packaging process is stopped if there is evidence that the mean amount packaged is different from 8.17 ounces. Suppose that in a particular sample of 50 packages, the mean amount dispensed is 8.159 ounces, with a sample standard
deviation of 0.051 ounce.
a. Is there evidence that the population mean amount is
different from 8.17 ounces? (Use a 0.05 level of significance.)
b. Determine the p-value and interpret its meaning.

9.48 Southside Hospital in Bay Shore, New York, commonly conducts stress tests to study the heart muscle after a person has a heart attack. Members of the diagnostic imaging department conducted a quality improvement project with the objective of reducing the turnaround time for
stress tests. Turnaround time is defined as the time from when a test is ordered to when the radiologist signs off on the test results. Initially, the mean turnaround time for a stress test was 68 hours. After incorporating changes into the stress test process, the quality improvement team collected a sample of 50 turnaround times. In this sample, the mean turnaround time was 32 hours, with a standard deviation of 9 hours. (Data extracted from E. Godin, D. Raven, C. Sweetapple, and F. R. Del Guidice, “Faster Test Results,” Quality Progress, January 2004, 37(1), pp. 33–39.)
a. If you test the null hypothesis at the 0.01 level of significance, is there evidence that the new process has reduced
turnaround time?
b. Interpret the meaning of the p-value in this problem.

9.55 The U.S. Department of Education reports that 46% of full time college students are employed while attending college. (Data extracted from “The Condition of Education 2009,” National Center for Education Statistics, nces.ed.gov.) A recent survey of 60 full-time students at Miami University found that 29 were employed.
a. Use the five-step p-value approach to hypothesis testing and a 0.05 level of significance to determine whether the proportion of full-time students at Miami University is different from the national norm of 0.46.

b. Assume that the study found that 36 of the 60 full time students were employed and repeat (a). Are the conclusions the same?

(b) Determine the P-value for this test. Show all work; writing the correct P-value, without
supporting work, will receive no credit.
(c) Is there sufficient evidence to justify the rejection of 0 H at the significance level of 0.05?
Explain.

1. If an experiment is conducted with 5 conditions and 6 subjects in each
condition, what are dfn and dfe?
2. The following data are from a hypothetical study on the effects of age and time on scores on a test of reading comprehension. Compute the analysis of variance summary table.
3. A researcher wants to know if the mean times (in minutes) that people watch their favorite news station are the same.
Suppose that Table 13.24 shows the results of a study.


Assume that all distributions are normal, the four population standard deviations are approximately the same, and the data
were collected independently and randomly. Use a level of significance of 0.05.

4. Are the mean number of times a month a person eats out the same for whites, blacks, Hispanics and Asians? Suppose
that Table 13.26 shows the results of a study.

Assume that all distributions are normal, the four population standard deviations are approximately the same, and the data
were collected independently and randomly. Use a level of significance of 0.05.
