Hey There!:

Sample Mean = 4.4823

SD = 0.1859

Sample Size (n) = 7

Standard Error (SE) = SD/root(n) = 0.0703

alpha (a) = 1-0.99 = 0.01

t(a/2, n-1 ) =  3.7074

Margin of Error (ME) =  t(a/2,n-1)x SE = 0.2606

99% confidence interval is given by:

Sample Mean +/- (Margin of Error)

4.4823 +/- 0.2606 = (4.222 , 4.743)

Hope this helps!

marta [7]

Answer:

$48,000

Explanation:

The computation of the total amount paid to the preferred shareholder is shown below:

= Number of preferred stock shares × par value × dividend rate × number of years

= 1,200 shares × $100 × 10% × 4 years

= $48,000

Simply we multiplied with the number of preferred stock with the par value, its dividend rate and the time period so that the correct value can come

Denver Company, a calendar year corporation, had the following actual income before income tax expense and estimated effective a
lara [203]

Answer:

Denver Company

Income Tax Expense for the second quarter:

Pre-tax quarter income = $140,000

Estimated tax rate = 24%

Tax Expense = $140,000 x 24%

= $33,600

Explanation:

a) Data:

Quarter    income before tax        estimated tax rate

first                 $100k                          30%

second           $140k                          24%

b) Denver's quarter second income tax expense is the product of the pretax income for the second quarter and the estimated income tax rate for the quarter.  The resulting calculation shows the estimated income tax expense that has to be settled by Denver.  If it is not settled in the quarter second period, it has to be carried forward to the next quarter as a liability under the heading, Income Tax Payable.

True or false: standard rules exist to help managers identify appropriate allocation bases.
tangare [24]

False, standard rules doesn't exist to help managers identify appropriate allocation bases.

Standard Rules refers to strong moral commitments or ethics that allows smooth working of an organisation. It is basically fundamental requirements to govern an organisation. It could play a role in appropriate allocation bases but doesn't exist for it rather to keep check on principles and equality in an organisation. They are not legally binding. But, appropriate allocation bases require judgement. Managers use- the direct method or the sequential (or step) method or the reciprocal method, to develop judgements about allocation bases. Hence, the statement is false.

(Predetermined OH rates; capacity measures) Albertan Electronics makes inexpensive GPS navigation devices and uses a normal cost
Jet001 [13]

Answer:

Albertan Electronics

a. Albertan Electronics’ predetermined variable OH rate is $20.50.

b. The predetermined FOH rate using practical capacity is $8.00.

c.  The predetermined FOH rate using expected capacity is $12.00.

d1.  The variable overhead applied is $1,375,000.

d2. The fixed overhead applied using the rate in (b) is $880,000.

d3. The fixed overhead applied using the rate in (c) is $1,320,000.

d4. The total under-applied overhead for 2010 at $8.00 FOH rate is $455,000 and the total under-applied overhead for 2010 at $12 FOH rate is $15,000.

Explanation:

a) Available 2010 budgeted data:

Variable factory overhead at 100,000 machine hours $1,250,000 ($12.50)

Variable factory overhead at 150,000 machine hours 1,875,000 ($12.50)

Fixed factory overhead at all levels between 10,000 and 180,000 machine hours  = 1,440,000 ($8.00)

Practical capacity is 180,000 machine hours; expected capacity is two-thirds of practical (120,000) = $12 ($1,440,000/120,000)

Predetermined Overhead Rate:

Variable factory overhead =         $12.50

Fixed factory overhead =                 8.00

Predetermined overhead rate = $20.50

During 2010, the firm records 110,000 machine hours and $2,710,000 of overhead costs. How much variable overhead is applied? How much fixed overhead is applied using the rate found in part (b)? How much fixed overhead is applied using the rate found in part (c)? Calculate the total under- or overapplied overhead for 2010 using both fixed FOH rates.

Variable overhead applied = $12.50 * 110,000 =    $1,375,000

Fixed overhead applied with $8 * 110,000 =               880,000

Total overhead applied                                          $2,255,000

Underapplied overhead = ($2,710,000 -2,255,000) 455,000

Variable overhead applied = $12.50 * 110,000 =    $1,375,000

Fixed overhead applied with $12 * 110,000 =           1,320,000

Total overhead applied                                          $2,695,000

Underapplied overhead = ($2,710,000 -2,695,000)    15,000
