A consumer magazine has contacted a simple random sample of 58 owners of a certain model of automobile and asked each owner how many defects had to be corrected within the first 2 months of ownership. The average number of defects was 4.9 with a sample standard deviation of 2.1 defects. Construct the 90% confidence interval for the population mean.

Answers

Answer 1

Answer:

(4.439 ; 5.361)

Explanation:

Given :

Confidence level = 90%

α = (1 - 0.9) / 2 = 0.05

Sample size (n) = 58

Degree of freedom (df) = n - 1 = 58 - 1 = 57

Mean number of defect (m) = 4.9

Standard deviation (s) = 2.1

m ± t0.05, 57 * (s /√n)

t0.05, 57 = 1.672029 (t value calculator)

4.9 ± 1.672 * (2.1 /√58)

4.9 ± 0.4610431

4.9 - 0.4610431 ; 4.9 + 0.4610431

(4.4389569 ; 5.3610431)

(4.439 ; 5.361)

A building was constructed in August 1999 for $2,340,000. The cost index at that time was 192.3. The current cost index is 302.1. What is the indicated cost new of the building today

Answers

Answer:

$3,676,100

Explanation:

in base year dollars, the building costed $2,340,000 / 1.923 = $1,216,849

if today's cost index is 3.021, then it should cost $1,216,849 x 3.021 = $3,676,100 to build the same building.

The cost index is used to adjust inflation, since costs tend to increase a little every year, you need some type of index to compare costs over different periods of time.

Debit Salary expenses for $5,750,000; Credit Bank for $3,750,000; and Credit PAYE payable for $2,000,000.

Explanation:

On 25 September, the journal entries will look as follows:

Sep. 25       Salary expenses          5,750,000

                    (To record total gross salary.)

Saffron Industries most recent balance sheet reports total assets of $42,000,000, total liabilities of $16,000,000 and stockholders' equity of $26,000,000. Management is considering using $3,000,000 of excess cash to prepay $3,000,000 of outstanding bonds. What effect, if any, would prepaying the bonds have on the company's debt-to-equity ratio

Answers

Answer:

A) Prepaying the debt would cause the firm's debt-to-equity ratio to improve from .62 to .50.

Explanation:

The computation of the impact is as follows:

The Debt equity ratio is

= Total liabilities ÷ total equity

Now

Debt equity prior to payment is

= $16,000,000 ÷ $26,000,000

= 0.62

And,

Debt equity after payment is

= $13,000,000 ÷ $26,000,000

= 0.50

So here as we can see that the debt equity would be improved from 0.62 to 0.50

Therefore the correct option is a.

During January, Ajax Co. Incurs 1,850 hours of direct labor at an hourly cost of $11.80 in producing 1,000 units of its finished product. Ajax standard labor cost per unit of output is $22 (2 hours x $11.00). Compute the total, price, and quantity labor variances for Ajax Co. For January. Identify whether the variance is favorable or unfavorable?

Answers

Answer:

Std rate per hour: 11.00    

Std hours = 1000*2 =2000    

Actual hours = 1850      

Actual rate = 11.80

   

Labor cost variance = Std cost - Actual cost    

Labor cost variance  = (2000*11) - (1850*11.80)

Labor cost variance = 170 Unfavorable

Labor rate variance = Actual hrs (Std rate - Actual rate)  

Labor rate variance = 1850 *(11-11.80)

Labor rate variance = 1480 Unfavorable

Labor qty variance = Std rate (Std hrs-Actual hrs)  

Labor qty variance = 11 (2000-1850)

Labor qty variance = 1650 Favorable.

You plan to make a series of deposits in an interest-bearing account. You will deposit $1,000 today, $2,000 in 2 years, and $8,000 in 5 years. If you withdraw $3,000 in 3 years and $5,000 in 7 years, how much will you have after eight years if the interest rate is 9%?

Answers

Answer:

$5,641

Explanation:

DEPOSIT NOW  

$1000 * FVIF 9%,8 PERIODS

= $1000 * 1.9926

= $1992.6

IN 2 YEARS

= $2000 * FVIF 9%,6 PERIODS

= $2000 * 1.6771

= $3354.20

IN 5 YEARS

= $8000 * FVIF 9%, 3 PERIODS

= $8000*1.2950

= $10360

WITHDRAWAL: IN 3 YEARS

= ($3000) * FVIF 9%, 5 PERIODS

= ($3000) * 1.5386

= ($4615.80)

IN 7 YEARS

= ($5000) * FVIF 9%, 1 PERIOD

= ($5000) * 1.0900

= ($5450)

Total value = $1992.6  + $3354.20 + $10360  - $4615.80 - $5450

Total value = $5,641

So, the total future value after eight years is $5,641

Submit your 300-word essay that thoroughly analyzes a problem that was solved through social media and provides your opinions on the impact social media use had on the issue. a definition of the problem-- what it is; an analysis of the problem-- what caused it and what the major issues are; how social networking was used to solve the problem; your opinions on how social media made it easier to solve the problem; and your sources.

Answers

Explanation:

Social media are tools that significantly impacted the relationship between companies and consumers, one could even say that they revolutionized this relationship.

Companies managed to get closer to their target audience in order to build a relationship that means increasing brand value, consumer loyalty and engagement on social networks. The so-called relationship marketing is a double path with benefits for both the client and the company, due to the fact that with greater proximity between them, there is a greater possibility for the client to have their issues with the brand resolved in less time, as for the brand to carry out instant and cheap advertising that reaches its potential audience almost at the same time.

Therefore, a problem that may have arisen, for example, a product purchased through a website that came with a manufacturing defect can be communicated directly to the company through its social media and the consumer can get a much quicker and less answer bureaucratic, and thus be able to exchange that piece or guarantee the refund of your money and solve your problem much more easily.

A coupon bond which pays interest semi-annually, has a par value of Rs.1,000, matures in 5 years, and has a yield to maturity of 8%. If the coupon rate is 10%, the intrinsic value of the bond today will be __________.

Answers

Answer:

Rs.1,081.10  

Explanation:

The intrinsic value of the bond today is the present value of the bond's future cash flows discounted at the appropriate yield which in this case is the semiannual yield to maturity since the bond pays coupons twice a year.

Using the bond price formula below, the bond price is computed thus:

Bond price=face value/(1+r)^n+semiannual coupon*(1-(1+r)^-n/r

face value=Rs.1,000

r=semiannual yield to maturity=8%*8/12=4%

n=number of semiannual coupons in 5 years=5*2=10

semiannual coupon=face value*coupon rate*6/12=1000*10%*6/12=50

bond price=1000/(1+4%)^10+50*(1-(1+4%)^-10/4%

bond price=1000/(1.04)^10+50*(1-(1.04)^-10/0.04

bond price=1000/1.48024428 +50*(1-0.67556417 )/0.04

bond price=1000/1.48024428 +50*0.32443583 /0.04

bond price= 675.56+405.54 = Rs.1,081.10
