The value of the investment of $2500 for 3 years will be $3703.86.
<h3>What is compound interest?</h3>
Compound interest is applicable when there will be a change in principle amount after the given time period.
For instance, if you give someone $500 at a 10% yearly rate, $500 is considered your primary sum. After a year, the interest will be $50, making the principle amount $550. Moving forward, the interest will be $550 rather than $500.
Given,
Principle amount (P) = $2500
Rate of interest (R) = 14%.
Time period (T) = 3 years.
Compound interest formula
A = P
So,
A = 2500[1 + 14/100]³
A = $3703.86
Hence the investment of $2500 at a rate of 14% for 3 years will be $3703.86.

Answer:
a) Since we have sample data and we don't know the population deviation we can use the t distribution in order to test the hypothesis
t would represent the statistic
b) (1)
The degrees of freedom are given by Replacing the info given we got:
c)
Since the p value is higher than the significance level we don't have enough evidence to conclude that the true mean of enrollment is significantly higher for four year college than for two year college
Step-by-step explanation:
Information given
represent the mean for two year colleges
represent the mean for four year college
represent the sample standard deviation for 1
represent the sample standard deviation for 2
sample size for the group 2
sample size for the group 2
Significance level provided
Part a
Since we have sample data and we don't know the population deviation we can use the t distribution in order to test the hypothesis
t would represent the statistic
Part b
We want to test if the mean of enrollment for four year college is higher than for two year college, the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
The statistic is given by:
(1)
The degrees of freedom are given by Replacing the info given we got:
Part c
The p value would be given by:
Since the p value is higher than the significance level we don't have enough evidence to conclude that the true mean of enrollment is significantly higher for four year college than for two year college
