2. A sample of 81 observations is taken from a normal population with a standard deviation of
5. The sample mean is 40. Determine the 95% confidence interval for the population mean.

Answers

Answer 1

If a sample of 81 observations are taken from a normal population. The sample mean is 40, and the sample standard deviation is 5. The 95%  confidence interval for the population mean is: 38.911, 41.089.

Confidence interval

Using this formula

Confidence interval=Sample means± (z-score× Standard deviation/√Sample size)

Let plug in the formula

The corresponding z-scores for 95% confidence interval is ± 1.96

Hence:

Confidence interval=40± (1,96×5÷√81)

Confidence interval=40± (1.96×5÷9)

Confidence interval=40± (1.96×0.5555)

Confidence interval=40± 1.089

Confidence interval=(40-1.089); (40+ 1.089)

Confidence interval=38.911, 41.089

Therefore If a sample of 81 observations are taken from a normal population. The sample mean is 40, and the sample standard deviation is 5. The 95%  confidence interval for the population mean is: 38.911, 41.089.

Answers

Answer:

If you invest $1,600 at the end of every year for four years at an interest rate of 14%, the balance of your investment in 4 years will be closest to:____________

$7,873.83

Explanation:

a) Data:

Annual investment = $1,600

Interest rate = 14%

Number of period = 4 years

b) Calculations, using an online finance calculator:

FV (Future Value) $7,873.83

PV (Present Value) $4,661.94

N (Number of Periods) 4.000

I/Y (Interest Rate) 14.000%

PMT (Periodic Payment) $1,600.00

Starting Investment $0.00

Total Principal $6,400.00

Total Interest $1,473.83

c) The investment of $1,600 at the end of every year for fours will grow to $7,873.83 with the principal amount of $6,400 ($1,600 * 4) plus compounded interest of $1,473.83.

Consider an Erlang loss system. The average processing time is 3 minutes. The average interarrival time is 4 minutes. The number of servers is 2. What is the rate of lost demand in customers per hour?
A. 1.33
B. .65
C. 1.5
D. 2

Answers

Answer:

D. 2

Explanation:

The computation of the rate of lost demand is shown below;

Given that

p = 3

a = 4

M  =2

Now

r = p ÷ a

=3 ÷ 4

= 0.75

Now determine the value from the erlang table having r = 0.75 and M = 2

= 0.123  

Now,

The  Rate of lost demand is

= demand rate × 0.123 × 60minutes

= (1 ÷ 4) × 0.123 × 60

= 1.845 or 2

= 2

Hence, the correct option is d.

The calculated rate of lost demand in customers per hour is 2.

Given Data

Average processing time (p) = 3

Average interarrival time (a) = 4

Number of servers (m)  =2

r = p/a

r = 3/4

r = 0.75

The value derived from erlang table having r = 0.75 and M = 2 is 0.123.

 

The formula to be used to derive the Rate of lost demand is {Demand rate * P(r,m) * 60 minutes)

Rate of lost demand = (1/4) * 0.123 * 60

Rate of lost demand = 1.845

Rate of lost demand =  2

Therefore, the Option D is correct because the calculated rate of lost demand in customers per hour is 2.

Papa PePe's Pizza purchased a used pizza oven for $9785. The company makes a down payment of $1000 and agrees to 36 monthly payments of $278.45 per month. Find the total finance charge.

Answers

Answer:

$1,239.2

Explanation:

finance charge refer the cost of using credit funds. It is the total amount a borrower pays to lender on top of the amount borrowed.

In this case, the total amount the customer paid for the oven

The deposit $1000.00

Monthly installment; $278.45 x 36= $10,024.2

Total amount paid =$278.45 +$10,024.2

=11,024.2

finance charge =  total amount paid - cost of the item

= $11,024.2 - $9,785.

=$1,239.2

A common bracket can be purchased in large quantities for $0.67. The company can make the bracket at a variable cost of $0.41 by buying a machine for $33,000. Demand over the next two years (the anticipated life of the product and machine) is estimated to be normally distributed with mean 100,000 units and a standard deviation of 10,000 units. Would you recommend making or buying this bracket?

Answers

Answer:

we recommnend to buy this bracket

Explanation:

The computation is shown below:

Given tyhat

Buying cost of the machine = $33,000 = x

x_1 = $0.67

And, x_2 = $0.41

Now the break even point is

X = x ÷ (x_1 - x_2)

= $33,000 ÷ ($0.67 - $0.41)

= 126,923 units

Therefore

Probability  (Demand > Break even point)

= 1 - [tex]\phi[/tex] ($126,923 - 100,000) ÷ 10,000

= 1 - [tex]\phi[/tex] (2.69)

= 0.36%

where

[tex]\phi[/tex] = function of cumulative distribution of N (0,1)

Therefore the probability is that it makes economically the items would be lesser

Thus, we recommnend to buy this bracket

Answers

Answer:

A corporation:

C. Is subject to federal income taxes on its earnings, whereas a partnership is not.

Explanation:

The other options fit a partnership more than a corporation.  The chief advantages of a corporation over a partnership are the limited liability status of the shareholders of a corporation, which benefits all the shareholders and secondly, the corporation is a separate legal entity from the owners.  This second advantage allows professional managers to lead the company.  With respect to federal income taxes on the earnings, the corporation is taxed directly on its earnings and shareholders also pay taxes on their income from all sources (unless it is an S-corporation), while partners in a partnership enjoy pass-through taxation of their partnership earnings.

Amanda's utility function is given by the equation u=10x+27, where x is the only good she is interested in purchasing. Given this information, what would Amanda's utility level be if she consumed one unit of x?

Answers

Answer:

37

Explanation:

From the given information;

if the utility function is given by:

u = 10x + 27

where;

x = one unit ( i.e. the quantity of the good she is interested in buying)

Then,

u = 10 (1) + 27

u = 10 + 27

u = 37

Thus, Amanda utility level if she consumed one unit of x = 37

Suppose a change in health care laws increases the cost of hiring an employee. We can expect output in the short run to __________ and output in the long run to __________.

Answers

Answer: decrease, be unaffected.

Explanation:

We should note that the output in the short run can be expected to reduce in the short run. This is due to the increase in the cost of employing an employee as there's at least a fixed input in the short run.

Subsequently, since the output is variable in the long run and not fixed like that of the short run, the output won't be unaffected in the long run.

Benefits like improved water quality and air quality, increases in biodiversity and habitat protection, and reductions in greenhouse gases (GHG), are all inherent in a strategy that protects and preserves land

Answers

Explanation:

This statement is correct. In reference to organizations, we can say that environmental management is increasingly a requirement for stakeholders when relating to a company, so there is an exponential growth of companies that seek to adopt more sustainable parameters in their production processes in order to reduce their impacts by environment to thus demonstrate to consumers and investors a company image that is concerned with positively developing society.

So there are some barriers that make the adoption of environmental processes more difficult in organizations, such as the difficulty of measuring environmental impacts, since many factories pollute the air in their production processes, for example, which is a factor that is difficult to measure.

The companies' focus then is to significantly reduce these impacts, and not just quantify them, this can be done through environmental programs, such as the Environmental Management System and ISO 14000 standards, which standardize processes and provide policies and procedures for the organization to adapt and achieve continuous improvement in its processes that contribute to the improvement of the environment as a whole.
