Answer:
so correct option is c. 1.51
Explanation:
given data
random sample n = 81
average speed x = 60 mph
standard deviation σ = 13.5 mph
interval estimate μ = 86.9%
to find out
the value of the z
solution
we have given μ = 86.9%
so we get here z critical value for the confidence level = 86.9 %
we will use here standard normal table
so z value for 86.9% is 1.51
so correct option is c. 1.51
Answer:
fixed cost = 11.026,6
Explanation:
we will use the High-Low method to sovle for variable and fixed component of utilities:
We subtract the high form the low
![\left[\begin{array}{ccc}High&2710&34712\\Low&2200&30255\\Diference&510&4457\\\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7DHigh%262710%2634712%5C%5CLow%262200%2630255%5C%5CDiference%26510%264457%5C%5C%5Cend%7Barray%7D%5Cright%5D)
510 hours generates 4,457 cost in utilities.
so variable cost:
4,457 / 210 = 8.74
Then we solve for fixed cost:
total cost = variable cost x Q + fixed cost
34,712 = 8.74(2,710) + fixed cost
fixed cost = 11.026,6
Given a histogram which is stewed to the right.
If a histogram is skewed, the median (Q2) is a better estimate of the
"center" of the histogram than the sample mean.
Therefore, the median and the quartiles are the best <span>measure of center and variability would be most appropriate to report for this distribution.</span>
Answer:
a. Savers who lend money are willing to accept a lower minimum interest rate than potential savers who do not lend money.
b. Investment projects that are financed by savers have larger rates of return than projects that do not receive financing.
Explanation:
Loanable funds refer to the aggregate amount of money that all sectors, entities and individuals within an economy have decided to keep as an investment, instead of spending on personal consumption, by saving and giving them out as loans to borrowers.
The market for loanable funds is in equilibrium when the supply of loanable funds by the saver is equal to demand for loanable funds by the borrowers at a given interest rate.
When the market for loanable funds is in equilibrium, efficiency is maximized because projects that have higher rates of return are given priority to be funded first before the projects with lower rates of return are funded. The reason is that savers that have lowest costs of lending provides funds for the projects that have highest return rates in equilibrium. However, potential saver who do not lend money will prefer a higher interest rates.
Therefore, the correct options related to the two aspects of efficiency that the equilibrium of market for loanable funds exhibits are as follows:
a. Savers who lend money are willing to accept a lower minimum interest rate than potential savers who do not lend money.
b. Investment projects that are financed by savers have larger rates of return than projects that do not receive financing.
