Answer:

± 4.05

Explanation:

Data provided in the question:

Random sample size = 15

Standard deviation = 8

Confidence level = 95%

Now,

Margin of error is given as:

Margin of error = ± [ ( z × s ) ÷ √n ]

Here,

From standard z table for 95% confidence level z = 1.96

Margin of error = ± [ ( 1.96 × 8 ) ÷ √15 ]

or

Margin of error = ± [ 15.68 ÷ 3.873 ]

or

Margin of error = ± 4.05

AURORKA [14]

Answer: B. One asset would increase $1,750 and a different asset would decrease $1,750, causing no effect

Explanation:

From the information given in the question, the journal entry at the time of sales will be represented as:

Debit Accounts receivable $1,750

Credit Sales $1750

Now, when the credit receipt is received as illustrated in the question, the journal entry will be:

Debit Cash $1,750

Credit Accounts receivable $1,750

Therefore, one asset would increase $1,750 and a different asset would decrease $1,750, causing no effect.

The correct option is B.

Assume that the reserve requirement is 10%. All other things being equal, will the money supply expand MORE if the Fed buys $1,0
Strike441 [17]

Solution:

The reserve ratio is 10%.

Money multiplier = \frac{1}{reserve requirement } = \frac{1}{0.10}  = 10.

So, the money multiplier increases by 10.

Money supply = amount x money multiplier = 1,000 x 10 = 10000

Therefore, because any certain items are equivalent, the rise in the currency supply is 10000 dollars.

When the FED sells 1,000 million worth of debt, this would further increase the monetary market, as the investments are fresh funds and the income from the bank is now used in the money supply.

= $53,730,000
