The test that we have here is a one tailed test. The decision rule is to Reject H0 when z > 1.282. the value of the test statistic is 1.56. The p value is 0.0594

<h3>How to solve the problem</h3>

a. The question that we have been asked to solve in the problem that we have here has been identified as a one tail test. The first option is correct

b. The decision rule that we are to abide by in the question is Reject H0 when z > 1.282. The first option is the answer here

c. How to solve for The z test statistic calculation

19 - 18 / 4 / √39

= 1.5612

e1. The p value that we have here is 0.059238. The p value was obtained through the use of a statistical software.

e2. The p value is less than 0.10. That is 0.059238 < 0.10 so we have to reject the null hypothesis.

If employers use a test to try to predict future job performance, it is vital that the test have ______ to ensure that it actual
Semenov [28]

Answer:

The correct answer is Validity.

Explanation:

The objective of the evaluation of the labor performance is to know the performance of a worker in the responsibilities that correspond to him, his abilities, knowledge, etc. as well as to detect possible inefficiencies and points for improvement. Often, it is also used to analyze the progress of an employee after joining the team, after a certain time or periodically, to see how they are working in their job, their development, and if the experience acquired or the Work performed corresponds to the objectives expected to be met.

Along the same lines, job performance is also evaluated in order to make decisions that affect salary increases, promotions, layoffs, incentives, and other issues that determine the present and future of a worker in the company.

In order for the performance evaluation to be valid and provide us with the most realistic results possible, it is advisable to follow certain basic rules:

  1. The employee must know that he is being evaluated and must know the objectives based on which his performance is being measured.
  2. The indicators to be measured must be adapted to each job position and supported by information relevant to their position and the tasks performed.
  3. It is preferable that the person in charge of the evaluation belongs to the team and is in direct contact with the worker, to know their evolution first hand and help them in their development.

nordsb [41]

Answer:

$13,290.89  and $15,734.26

Explanation:

In this question we have to use the Present value function which is shown on the attachment below:

In the first case

Provided that

Future value = $0

Rate of interest = 12%  ÷ 12 months = 1%

NPER = 48 months

PMT = $350

The formula is shown below:

= PV(Rate;NPER;PMT;FV;type)

So, after solving this, the present value is $13,290.89

In the second case

Provided that

Future value = $0

Rate of interest = 12%  ÷ 12 months = 1%

NPER = 60 months

PMT = $350

The formula is shown below:

= PV(Rate;NPER;PMT;FV;type)

So, after solving this, the present value is $15,734.26

Registered bonds - The bondholder's referent information is held by the issuer the main purpose of which is to ensure that payments are going to the right address.

Bearer or coupon bonds - These types of bonds can be transferred from one owner to another as the bond is not recorded in the holder's name.

Convertible bonds - These bonds are convertible into shares in the issuing company.

Commodity-backed bonds - Such bonds are valued based on the value of a certain asset that will be specified in the agreement.

Deep discount bonds - This kind of bond is sold at 80% or less than its face value.
