Problem P5-2: Future Value Calculation

In this problem, we are asked to compute the future value of $1 over different interest rates and periods without using preprogrammed functions in a financial calculator, but rather applying the fundamental future value formula:

FV = PV × (1 + r)^n

where PV is the present value, r is the interest rate, and n is the number of periods. Given the interest rates and periods for each case, we proceed as follows:

  • Case A: r = 12%, n = 2
  • Case B: r = 6%, n = 3
  • Case C: r = 9%, n = 2
  • Case D: r = 3%, n = 4

Applying the formula:

Case A: FV = 1 × (1 + 0.12)^2 = 1 × 1.2544 = 1.2544

Case B: FV = 1 × (1 + 0.06)^3 = 1 × 1.191016 = 1.1910

Case C: FV = 1 × (1 + 0.09)^2 = 1 × 1.1881 = 1.1881

Case D: FV = 1 × (1 + 0.03)^4 = 1 × 1.1255 = 1.1255

These calculations can be performed in Excel by inputting the respective values and applying the formula in each sheet or using Excel’s FV function for confirmation.

Problem P5-6: Future Car Price Estimation

This problem involves estimating the future price of a car based on current price and inflation rates over five years.

Given current price = $14,000

Inflation rates: 2% and 4% annually

a) To estimate the future price:

  • At 2% inflation: FV = PV × (1 + 0.02)^5 = 14,000 × 1.10408 ≈ $15,457
  • At 4% inflation: FV = 14,000 × 1.21665 ≈ $17,032

b) The difference in future price: $17,032 - $15,457 ≈ $1,575

c) If inflation is 2% for first 2 years and 4% for remaining 3 years, then:

  • For first 2 years: 14,000 × 1.02^2 = 14,000 × 1.0404 ≈ $14,565
  • Subsequently, for 3 years at 4%: 14,565 × 1.21665 ≈ $17,735

This approach accounts for changing inflation rates over different periods.

Problem P5-14: Bond Future Value

Considering a bond that matures to $100 in 6 years, and pays 8% annual interest compounded annually.

To find the present price (purchase price), use the present value formula:

PV = FV / (1 + r)^n = 100 / (1 + 0.08)^6 ≈ 100 / 1.58687 ≈ $63.02

This means the bond must be sold at approximately $63.02 today to be competitive with other bonds paying 8% interest.

Problem P5-22: Retirement Planning

This problem explores the effects of different deposit timings and start ages on retirement savings.

a) If $2,000 is deposited annually at the end of each year for 40 years at 10%, the accumulated value using the future value of an ordinary annuity:

FV = P × [(1 + r)^n - 1] / r = 2000 × [(1.10)^40 - 1] / 0.10 ≈ $646,416

b) If deposits start at age 35 instead of 25, only for 30 years (from 35 to 65):

FV = 2000 × [(1.10)^30 - 1] / 0.10 ≈ $155,690

c) Comparing both, delaying deposits by 10 years results in significantly lower accumulation, illustrating the importance of early savings.

d) If deposits are made at the beginning of each year (annuity due), the future value is higher by approximately 10% due to the additional period of interest accumulation.

In essence, beginning deposits earlier and making them at the start of each period greatly enhances total savings, highlighting the power of compound interest and early investment.

Problem P5-29: Single Amount vs. Mixed Stream of Payments

Gina plans to sell her land and can receive either $24,000 immediately or a series of payments over 5 years, with interest earned at 7% annually.

The future value of receiving $24,000 immediately in 5 years is calculated by:

FV = 24,000 × (1 + 0.07)^5 ≈ 24,000 × 1.40255 ≈ $33,662

For the mixed stream of payments beginning at the start of each year, the future value is the sum of each payment compounded to the 5-year horizon:

  • Year 1: $2,000 × (1.07)^4 ≈ $2,000 × 1.3108 ≈ $2,621
  • Year 2: $2,000 × (1.07)^3 ≈ $2,000 × 1.2250 ≈ $2,450
  • Year 3: $2,000 × (1.07)^2 ≈ $2,000 × 1.1449 ≈ $2,290
  • Year 4: $2,000 × (1.07)^1 ≈ $2,000 × 1.07 ≈ $2,140
  • Year 5: $2,000 × (1.07)^0 ≈ $2,000 × 1 ≈ $2,000

Adding these amounts: $2,621 + $2,450 + $2,290 + $2,140 + $2,000 ≈ $11,501

Plus accumulated interest, the total at year 5 is approximately $33,523, making it marginally higher than the lump sum amount of $33,662, which favors taking the immediate payment.

Problem P5-40: Compounding Frequency and Time Value

Investing $2,000 today at 8% interest with different compounding frequencies over 10 years:

  • Annually: FV = 2000 × (1 + 0.08)^10 ≈ 2000 × 2.1589 ≈ $4,317.84
  • Semiannually: FV = 2000 × (1 + 0.04)^20 ≈ 2000 × 2.1912 ≈ $4,382.41
  • Daily: FV = 2000 × (1 + 0.08/365)^{365×10} ≈ 2000 × 2.2255 ≈ $4,451.04
  • Continuously: FV = 2000 × e^{0.08×10} = 2000 × e^{0.8} ≈ 2000 × 2.2255 ≈ $4,451.04

The Effective Annual Rate (EAR) for each is calculated as:

  • Annual: 8%
  • Semiannual: (1 + 0.04)^2 - 1 ≈ 8.16%
  • Daily: (1 + 0.08/365)^{365} - 1 ≈ 8.33%
  • Continuous: e^{0.8} - 1 ≈ 125.32%

Continuous compounding yields the highest future value, demonstrating how increasing compounding frequency enhances growth. The EAR increases with more frequent compounding, illustrating the importance of compounding frequency in investment growth.

These calculations emphasize the critical role of compounding frequency on investments and the benefits of continuous compounding for maximizing returns.

Additional Problems: Hypothesis Testing and Research Design

Regarding research examples, each statistical technique can be applied in real-world studies. For instance:

  • Correlation: Examining the relationship between hours studied and exam scores among 200 students, predicting a positive correlation.
  • Multiple Regression: Assessing how study hours, attendance, and prior GPA predict final grades, involving 150 students.
  • T-Test for Independent Means: Comparing test scores between two different teaching methods with sample sizes of 50 each.
  • T-Test for Dependent Means: Measuring pre- and post-intervention health metrics within the same group of 30 patients.
  • ANOVA: Testing differences in customer satisfaction scores across three store locations with 100 participants each.
  • Chi-Square for Goodness of Fit: Determining if observed preferences for different food rewards align with expected distributions based on prior surveys.
  • Chi-Square for Independence: Investigating if preferred food reward types are independent of participant age groups.

When designing these studies, specify the sample size based on power analysis to ensure sufficient ability to detect effect sizes. Effect sizes provide a measure of the magnitude of observed effects, and power analysis helps determine the necessary sample size to achieve desired statistical power (usually 0.80), considering significance level and effect size.
