Answer:

The Confidence Interval(CI) is calculated as (0.043, 0.257).

The steps and expanation is shown below.

Explanation:

The formula for a Confidence Interval(CI) for a population proportion is given as

p + z*[Sqrt(p(1 - p))/n]

Or

p - z*[Sqrt(p(1 - p))/n],

p is the sample proportion, n is the sample size, and z* is the appropriate value from the standard normal distribution for your desired confidence level. The following table shows values of z* for certain confidence levels.

For the 98% Confidence Interval, z*–value = 2.33

p = 9/60 = 0.15, confidence level z* = 2.33( From the standard table)

0.15 + 2.33[Sqrt(0.15(1 - 0.15))/60]

OR

0.15 - 2.33[Sqrt(0.15(1 - 0.15))/60]

0.15 + 0.107 or 0.15 - 0.107

Confidence Interval is

(0.043, 0.257)

Answer:

= (0.043 , 0.257)

Explanation:

p = 9/60 = 0.15

Z score for 98% confidence interval = Z0.01 = 2.33

The Confidence interval = (p + Z0.01 * sqrt(p * (1 - p) / n))

= (0.15 + 2.33 * sqrt(0.15 * (1 - 0.15) / 60))

= (0.15 + 0.107)

= (0.043 , 0.257)

You are a member of a project team revising the Nvidia Corporation’s ethics policy. The team has representatives from five divis
vova2212 [387]

Answer:

B) The other members of the team are ineffective

Explanation:

The role of the corporate communications is a very important one; that department is responsible for how employees, investors, clients and the general public alike view an organization. The office of the corporate communications is also responsible for coordinating and handling all internal and external communication to the end that a better work environment is fostered; one which ensures the maximum productivity of the organization. As such, what we see here is that Audrey gives a feedback to the head of Corporate Communications who also doubles as the team leader of what can be done to enhance the optimal performance of the team. She suggests that a critical appraisal be done concerning the ethics policy of the company. Audrey is not insinuating that her work is undervalued evidenced by the fact that what she said would apply to all and not just her.  Nor does she seek to present new draft of the ethics policy, since she suggested that 'the team' handle the review. Audrey simply brings to the fore the fact that the team needs to be injected with a fresh dose of effectiveness.

<u>Hence, option B is the correct answer</u>

a. You wish to have $1,500,000 by the age of 60 (30 years from now). If you can earn 8% interest on your investments, how much d
lakkis [162]

Answer:

A) We need to save $1,005 per month in order to have 1,500,000 in 30 years.

B) We will be able to borrow 158,579

C) We will have 2,259,361 in 35 years

D) The equivalent amount of money is 12,585

Explanation:

A) We are given a future value that we need to have in 30 years. So our future value is 1,500,000. Our present value is 0, our interest rate is 8/12=0.667. We divide 8 by 12 because we need to save money per month. The number of compounding periods are (30*12)=360. We multiply by 12 because monthly payments. Now we will enter this information in a financial calculator to find future value.

Pv= 0

FV = 1,500,000

I=0.66

N=360

Compute PMT= 1,005

B) PMT= 900

   I=5.5/12=0.458

   N= 30*12=360

   FV=0

Compute PV

PV=158,579

C) PV= 100,000

    PMT= 300

     N= 35*12= 420

     I=8/12=0.66

Compute FV=2,259,361

D) We need to know how much money will we need 30 years from now if we want to buy goods and services which are worth 6,000 today considering an inflation rate of 2.5%

We will multiply 6000 by (1+Inflation)^number of years

6000*(1.025)^30

=12,585

AveGali [126]

1. Intrinsic reward

2. Intrinsic reward

3. Extrinsic reward

Explanation:

What is an intrinsic reward.: Intrinsic rewards are rewards that comes from within the employee. For example, personal achievement, professional growth, sense of pleasure and accomplishment.

What is an Extrinsic reward: Extrinsic motivation is gotten externally. External rewards are typically offered by an employer or manager.

1. )This is an intrinsic reward because no one with more that two years seniority will ne separated from the company except for poor performance. This poor performance clause will act as a motivation to make them perform better.

2. The regular feedback from Jonah's supervisor is an intrinsic reward because Johan will be able to evaluate his strength and weakness and know where to improve himself.

3. Health benefit is an extrinsic reward. This health benefit is offered by Dion's employer. So it is an external reward.
