Here, we are concerned about two variables from the above data set, namely, Condo or co-ops and the Unemployment rate. We use the CORREL function of Excel to calculate the correlation coefficient rate and it is = R = -0.01873.
A Weak (negative) correlation exists between the list price of condominiums and co-ops and the unemployment rate.
The correlation coefficient is a statistical measure of the strength of the connection between the relative actions of two variables. The values varied between -1.0 and 1. zero. A calculated wide variety greater than 1. zero or less than -1.zero means that there was an error within the correlation size.
The correlation coefficient is decided with the aid of dividing the covariance by way of the product of the 2 variables' popular deviations.
Correlation values above 0. eight are deemed to signify a strong tremendous linear courting between the variables. Values among zero and 0. three imply a vulnerable relationship or none.

Answer:
<u>The future value of this investment after 10 years is US$ 5,152.58</u>
Step-by-step explanation:
1. Let's review the data given to us for solving the question:
Investment = US$ 2,500
Annual interest rate = 7.5% compounded annually
Duration of the investment = 10 years
2. Let's find the future value of this investment after 10 years, using the following formula:
FV = PV * (1 + r) ⁿ
Replacing with the real values, we have:
FV = 2,500 * (1 + 0.075) ¹⁰
FV = 2,500 * 1.0075¹⁰
FV = 2,500 * 2.06103
<u>FV = US$ 5,152.58</u>
Multiply both sides by 2 to get 72, so x < 72
