Answers without corresponding work may not be graded correct or awarded any partial credit.  Present your work neatly, in an organized manner, with detail.This examination is due at the beginning of class on March 1, 2018. Late papers will not be accepted.Electronic submissions will not be accepted.Each of the  major questions is worth an equal amount. Your grade will be calculated on a percentage basis (from 0% to 100%). Partial credit may be given.1.) Calculate the simple interest for an investment with an initial principal of $10,500, an interestrate of 4.85% per year, and the time period of 3 years and 3 months. Show your work andanswer.2.) Calculate the compound interest for an investment with an initial principal of $10,500, aninterest rate of 4.85% per year, and a time period of 3 years 3 months. Compounding shouldbe donemonthly. Show your work and answer.3.)  Stephanie Garcia must pay a lump sum of $10,500 in 5 years. What amountdeposited today at 3.8% interest compounded annually will amount to $10,500 in 5 years?(Hint: Use the present value for compound interest formula.) Show your work and correctanswer.4.) What amount would need to be invested weekly (52 weeks per year) to have an investmentworth $1,500,000 in 30 years if the interest rate was 7.5%? Assume that the first investmentwould be made at the time that the investment plan was initiated (making this an annuity due).5.) The Anderson family buys a house for $325,000 with a down payment of $85,000. The familytakes out a 30 year amortized mortgage on the remaining cost of the home at an annual interestrate of 3.6%.  Payments (principal and interest) of equal amount are paid monthly. Find theamount of the monthly payment needed to amortize this loan. Show your work and correctanswer.6.) Consider the Anderson family’s purchase of a house described in problem #5. At the end of12 years the Andersons inherit some money and want to pay the remaining balance on theamortized loan. What would the this remaining balance?7.) You win a lottery prize that has a total value (after taxes) of $35,850,000. 30 yearly payments of$1,195,000 would be made if you took the winnings over the 30 year payout with the firstpayment being made immediately and the remaining equal payments being made yearly at thebeginning of each year. The lottery would buy an annuity which has an annual interest rate of5.2%. You elect the alternative and take the cash value of this annuity now. You calculate thatyou can make more money by investing the winnings at a higher rate than 5.2%. What is thecash value of this annuity?8.) You graduate from college and start work. You set up an investment plan whereby youcontribute $125 from each of your monthly paychecks and get 5.4% interest compoundedmonthly. You have your first payment payroll deducted and deposited into the IRA (individualretirement account)at the endof your first month’s work. If you intend to work for45 years, what will be the value of this investment when you retire?9.) You are buying a car that cost $26,500. You make payments of $412 each month for 4 years.The interest rate charged on the amount owed after you made the down payment is 2.9%per year. What will be the amount of your down payment?10.) When you save money in a bank savings account the interest is calculatedcontinually. Thisinvolves using a formula with e.  Assume that the annual interest rate is 3%. If you make aone- time deposit of $6,800 into this type of bank savings account,a.) What will be the total value in the account at the end of 5 years and 9 months?(3/4 credit)b.) What will be the amount of the interest earned at the end of 5 years and 9 months?(1/4 credit)11.) You have steady employment and earn a regular salary. You have saved $5400 that you wantto invest in a certificate of deposit that pays a stated rate (nominal rate) of 4.6%. The intereston this CD is compounded weekly (52 weeks in a year for banking purposes). What is effectiverate (annual percentage rate, APY)? (Hint: The effect rate should be greater than the nominalrate.)12.) Consider the future value of an ordinary annuity and an annuity due.a.) Explain the difference between these two types of annuities.b.) Which of these plans will produce a greater value at the end of the total time period for theannuity? Why is this so?(Answer thoroughly using complete sentences.)13.) Solve the following linear system using your graphing calculator and matrix commands. Giveyour answers and describe the process you used (the calculator steps) to find the solution.Hint: There is a definite solution to this system. It is not unsolvable.x – y + 5z = -63x + 3y – z = 10x + 2y + 3z = 514.) Solve the linear system shown in #13 above using the Gauss-Jordan method. Show all stepsone under anotheron the left in a single column and to the right show any needed calculationsand give the correct corresponding transition commands (Example: R1 <--- R1 + .5 R2). Detailis needed for credit. Work until you reach the row echelon format and back solve.To get you started:Show original system of 3 equations here.1st transition (Show complete new system.)  work for 1st transition and transitioncommand (as in the example shownabove)2nd transition work for 2nd transitionetc.(Show the remaining steps too.)Back solving work and answers here

Chapter 8Global Warming  In April 2011, a Yale/George Mason poll of 1010 US adults found that 40% of the people responding believed that scientists disagreed about whether global warming exists.  They reported a 95% confidence interval of 37% to 43%.What was the study’s margin of error?If the researchers  wanted to be 98% confident, would their confidence interval be wider or narrower?If the researcher wanted to reduce the margin of error, would they need to make their level of confidence higher or lower?If the researchers had polled more people, would the interval’s margin of error have been larger or smaller?MLB  In a sample of 30 current MLB pitchers, the mean age was 28 years with a standard deviation of 4.4 years.  Using StatCrunch, construct a 95% confidence interval to estimate the mean age of all current MLB pitchers.Give the interval, round values to 1 decimal place:___________________State the correct numerical values that would be in each of these numbered spots in this diagram of this confidence interval.Contributions Please  The Paralyzed Veterans of America is a philanthropic organization that relies on contributions.  They send free mailing labels and greeting cards to potential donors on their list and ask for a voluntary contribution.  To test a new campaign, they recently sent letters to a random sample of 100,000 potential donors on their mailing list and received 4781 donations.State the 95% confidence interval in correct conclusion sentence form for the true proportion of their entire mailing list who may donate.  Round values 3 decimal places.A staff member thinks that the true rate is 5.5%.  Given the confidence interval you found, do you find the staff member’s percentage plausible?  Explain why or why not.Chapter 9Living with Parents   Many young adults live at home with their parents due to various reasons, such as lack of income, postponing marriage, and saving money for school.  A recent survey reports that approximately 36% of all young adults (ages 18-31) live with their parents (Fry, 2013).  In order to check this claim, a random sample of 440 young adults was obtained and 183 of them were found to live with their parents. Is there sufficient evidence to conclude that the proportion of young adults who live at home with their parents is higher than the value the survey reported?  Use α = 0.01.What was the data that was collected in this problem?Is this quantitative data or qualitative data?State the value of the sample statistic rounded to 2 decimal places.State the value of the population parameter that is being tested in this problem.State the level of significance given in the problem.State the hypotheses using the correct statistical symbols.State the test statistic rounded to 2 decimal places.State the P-value rounded to 4 decimal places.What is the correct decision?In a complete sentence, indicate the strength of this P-value and give a conclusion using the SPECIFIC context of the problem that you are testing.  I should be able to read this conclusion sentence and know specifically what the test was about.
