Question

If an investment is made in a banking entity for an initial amount of 822,000.00 colones in 6 quarters, which obtains an annual return of 11%, but after that period it is decided to carry out a new one investment for 350,000.00 colones additional to the total received from the first investment with a new rate of interest, for 1500 days at a rate of 13%. What amount do you receive at the end of the period in its entirety?

1. Calculate the future value of the initial investment after 6 quarters with an annual return of 11%:
- The formula for future value is given by

A = P \left(1 + \frac{r}{n}\right)^{nt}

- Here,

P = 822,000 \, \text{colones}

,

r = 0.11

,

n = 4

(since interest is quarterly), and

t = 1.5

years (since 6 quarters = 1.5 years).
- Substitute the values:

A_1 = 822,000 \left(1 + \frac{0.11}{4}\right)^{4 \times 1.5}

A_1 = 822,000 \left(1 + 0.0275\right)^{6}

A_1 = 822,000 \times 1.171958

A_1 = 963,647.076

2. Calculate the future value of the new investment (initial total from step 1 + additional investment) after 1500 days at a rate of 13%:
- Convert 1500 days to years:

t = \frac{1500}{365}

years.
- Additional investment: 350,000 colones.
- New principal

P_2 = A_1 + 350,000

P_2 = 963,647.076 + 350,000

P_2 = 1,313,647.076

colones.
- Annual interest rate

r = 0.13

.
- Substitute the values in the future value formula:

A_2 = P_2 \left(1 + r\right)^t

A_2 = 1,313,647.076 \left(1 + 0.13\right)^{\frac{1500}{365}}

A_2 = 1,313,647.076 \times 1.529152

A_2 = 2,297,473.701

3. The total amount received at the end of the period is

2,297,473.701

colones.

The boxplot below is of the sodium contents levels taken from a random sample of 30 bottles. With this data investigate the claim using SPSS to apply the appropriate test. Download the data and transfer it into SPSS. Check that your data transfer has been successful by obtaining the Std. Error of the mean for your data which should appear in SPSS output as 0.03900.. If you do not have this exact value, then you may have not transferred your data from the Excel file to SPSS correctly. Do not continue with the test until your value agrees as otherwise you may not have correct answers. Unless otherwise directed you should report all numeric values to the accuracy displayed in the SPSS output that is supplied when your data has been transferred correctly.
