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!

zloy xaker [14]

Answer: A.) $32.64 per machine hour

Explanation:

Given the following :

Estimated machine hours = 41,000 machine hours

Estimated variable manufacturing overhead = $4.16 per machine hour

Estimated total fixed manufacturing overhead = $1,167,680

Total Estimated manufacturing overhead :

(Estimated total variable manufacturing overhead + Estimated total fixed manufacturing overhead)

Estimated total variable manufacturing overhead:

$4.16 × estimated hours

= $4.16 × 41,000

= $170560

Total Estimated manufacturing overhead :

$170560 + $1,167,680 = $1338240

Hence,

Predetermined overhead rate :

Total Estimated manufacturing overhead / estimated hours

= $1338240 / 41000

=$32.64

Smith entered an oral agreement hiring and authorizing Jones to sell fraudulent identification cards produced by Smith. Smith an
Marina CMI [18]

Explanation:

We have to note an important point here is that, Smith has plan to sell fraudulent identification card through Jones and he has done only Oral agreement.

An oral agreement does not have a proof. Any oral agreement cannot be taken as a proof legally. There must be a proper written agreement required to prove the relationship. There are certain standard too in written agreement.

For Example, agreement written on a normal white paper cannot be accepted. The agreement should be legally signed according the bond paper provided and authorized by the Government.

Considering all the above discussion, Jones stands right.

Dufner Co. issued 17-year bonds one year ago at a coupon rate of 7.3 percent. The bonds make semiannual payments. If the YTM on
Ierofanga [76]

Answer:

The current dollar price assuming a par value of $1,000 is $ 1,213.95

Explanation:

The current price is computed as shown below:

The coupon payments will be as follows:

= (7.3% ÷ 2) × $ 1,000 (Since the payments are semi annual, hence divided by 2)

= $ 36.5

YTM will be as follows:

= (5.3% ÷ 2) (Since the payments are semi annual, hence divided by 2)

= 2.65%  

N is computed as follows:

= (17 - 1 ) × 2 (Since the payments are semi annual, hence multiplied by 2)

= 32

So, the price of the bond will be as follows:

= Coupon payment x [ [ (1 - 1 / (1 + r)^n ] / r ] + Par value / (1 + r)^n

= $ 36.5 × [ ( 1 - \frac{1}{(1 + 0.0265)32} ] / 0.0265 ] + \frac{1000}{1.0265^{32}}

= $ 36.5 × 21.39526 + $ 433.0255

= $ 780.92699 + $ 433.0255

= $ 1,213.95
