Answer:

(196.97,187.03)

Explanation:  

Formula for Confidence interval is : avg repair bill (a) ± (Z×SD)÷√(sample size)

average repair bill (a) = $192

Z at 98% confidence level = 2.326

Sample Size = 14

Standard Deviation (SD) = $8  

Confidence Interval = 192 ± 2.326*8÷√(14) = {(192 + 4.97),(192 - 4.97)} = {196.97,187.03}

Anna71 [15]

Answer:

The answer is B.

Explanation:

Marginal Productivity can be described as when every variable in the equation is held constant, it is the amount of productivity gained for every extra hour of labor that is put in.

And according to the information about Joey and his productivity cutting the lawns, we are provided the equation q = 0.2*L which means that for every extra hour Joey works cutting the lawns, Joey's marginal productivity is going to decrease by 0.2 or 20% so the answer is B.

A bank's commitment (for a specified future period of time) to provide a firm with loans up to a given amount at an interest rat
sladkih [1.3K]

Answer:

credit rationing

Explanation:

Credit rationing is a situation in which borrowers give out a fixed amount of loan to lenders for a specified time at a rate tied to the market interest rate. In this situation, loans do not exceed a certain amount from the borrower no matter what attractive offers are given by the lenders to be able to get a larger loan amount. This is done by the borrower becasue the borrower is earning maximum profits from interest rates and also  is a means to maintain equilibrum between loan funds and loan demands.  

Cheers.
