Answer:

0.1640 ≤ p ≤0.3532

Explanation:

Sample size (N) = 58 customers

Z-score for 90% interval (Z) = 1.645

The proportion of customers that received some cash back is given by:

p=\frac{15}{58}\\p=0.2586

The confidence interval for the proportion of all depositors who ask for cash back is determined by the following relationship:

p\pm Z*\sqrt{\frac{p*(1-p)}{N}}

Applying the given data:

0.2586\pm 1.645*\sqrt{\frac{0.2586*(1-0.2586)}{58}}\\0.2586\pm0.0946

The upper and lower limits are:

L=0.2586-0.0946\\L =0.1640 \\L=0.2586-0.0946\\L = 0.3532

Using a 90% confidence level, the interval for the proportion (p) is:

0.1640 ≤ p ≤0.3532

tatuchka [14]

Answer:

WACC 13.85600%

Explanation:

First we calculate Eastern Pizza CAPM:

Ke= r_f + \beta (r_m-r_f)

risk free = 0.08

market rate = 0.12

premium market = (market rate - risk free) 0.04

beta(non diversifiable risk) = 2

Ke= 0.08 + 2 (0.04)

Ke 0.16000

Then we solve for WACC

WACC = K_e(\frac{E}{E+D}) + K_d(1-t)(\frac{D}{E+D})

Ke 0.16000

Equity weight 0.8

Kd 0.08

Debt Weight 0.2

t 0.34

WACC = 0.16(0.8) + 0.08(1-0.34)(0.2)

WACC 13.85600%

The company will use the data on eastern Pizza to evualuate project presented to it. Also, it will  consider the new tax rate to determinate the tax shield.

iren2701 [21]

Answer:

A. Increase liabilities (Accounts payable) by $337.8 million

Explanation:

The journal​ entry will be: Inventory (Credit - Increased) 337,860,000 and Accounts payable (Debit - Increased) 337,860,000.

The company must recognize the increase in the Inventory and the medium of payment (Accounts payable).

B is false because this operationn can also be a decrease in cash, but the amount in the operation is too high for this payment medium.

C is false because, the inventory is not sold, and COSG will be increased when the goods are sold.

D is also false because the inventory is increasing, not decreasing.

siniylev [52]

Companies may try to lower their labor costs by laying off higher paid workers.

Typically the higher paid workers will be professionals who have worked their way up over time and tend to be older, while younger workers fresh out of school and looking for their first jobs will be more willing to take lower salaries.

Answer:

ending work in process and the cost of units transferred out.

Explanation:

In a cost reconciliation schedule, costs accounted for is computed by adding the cost of the ending work in process and the cost of units transferred out.

The cost reconciliation schedule gives the relationship between total costs accounted for and total costs to be accounted for.

When the total costs accounted for equal the total costs to be accounted for, this is a cost reconciliation schedule.
