Answer: The mean of this distribution = 61.95
The standard deviation of this sampling distribution (i.e., the standard error= 0.048
Step-by-step explanation:
Given : Data from the U.S. Department of Education indicates that 59% of business graduate students from private universities had student loans.
i.e. proportion of business graduate students from private universities had student loans : p=0.59
sample size : n=105
Then , the mean of the distribution is given by :-

∴The mean of this distribution = 61.95
Then standard deviation of this sampling distribution is given by :-

∴The standard deviation of this sampling distribution (i.e., the standard error= 0.048
It took her 1 hour to get to the appointment; at 80mph that means the appointment was 80 miles away.
General Idea:
The measure of one of the central angles of a regular Polygon (
) can be used using the below formula:

Applying the concept:
The measure of one of the central angles of a regular octagon.
The octagon have 8 sides, using the above formula we get...

Conclusion:
The correct option is <em><u>A) 45 degrees</u></em>
The future value of the investment if the interest is compounded monthly is $89,354.89.
<h3>What is the future value of the investment?</h3>
Given that;
- Principal P = $20,000
- Annual interest rate r = 5% = 5/100 = 0.05
- Time t = 30 years
- Compound monthly = 12
- Future value = A = ?
Using the compound interest formula;
A = P( 1 + r/n )^(nt)
We plug in our values.
A = 20000( 1 + 0.05/12 )^(12 × 30)
A = 20000( 1 + 0.0041666666666667)^(360)
A = 20000( 1.0041666666666667)^(360)
A = 20000( 4.46774965 )
A = 89354.89
Therefore, the future value of the investment if the interest is compounded monthly is $89,354.89.
