Solution :
a). There are total 5 executives. Therefore the possible sample size of 2 is



= 10
So, there are 10 possible ways for selection of sample size of 2.
b).
Sample Samples of service length Sample mean
Snow, Tolson 20, 22 (20+22)/2 = 21
Snow, Kraft 20, 26 23
Snow, Irwin 20, 24 22
Snow, Jones 20, 28 24
Tolson, Kraft 22, 26 24
Tolson, Irwin 22, 24 23
Tolson, Jones 22, 28 25
Kraft, Irwin 26, 24 25
Kraft, Jones 26, 28 27
Irwin,Jones 24, 28 26
c). The mean and the standard deviation of the means of the sampling distribution is given by :


= 24
The variance of the sample means :



= 3
Therefore the standard deviation of the sample means is


= 1.732
d). The population means is given by:


= 24
Therefore, we can say that the mean of the sample means is a point estimate of the population mean.
Answer:
The correct answer is: Inventories.
Explanation:
Inventories are real and concrete assets, that is movable and immovable property. These form the commercial flow of a person or a company. These goods are for sale, hence the commercial nature, or for the consumption of goods and / or services. Inventories are made in a certain period of time.
If a company is commercial, its livelihood is always buying and selling, that is, the exchange of goods and services. With the inventory, the company has an exhaustive control of merchandise during the commercial period, and at the end of it it has the “final balance”, that balance is comparable with that of other years and serves to draw conclusions and from there take certain actions depending of the result. When the goods are being counted for a certain economic period, it is necessary that they appear in the “Current Assets” group, this means that it is all merchandise at the cost that is in the hands of a company.
The concept of inventory has to do with accounting, which is a system for controlling and recording profits (income and expenses), as well as economic operations, in this case carried out by a company or association, it reflects the financial movements that they make.

Answer:
<u>groupthink.</u>
Explanation:
Group thinking occurs when a group is struck by thoughts common to its members regarding conflict avoidance by establishing consensus without conducting a critical analysis of opinions and ideas.
The conformity of ideas is expected in the group's thinking, there is no interaction and innovation regarding new contributions to the achievement of the group's goals, except what is already usual and consensual by all members.
Usually this phenomenon occurs when there is fear on the part of the members to generate conflicts, or to contribute alternatives that may be seen as irrelevant and the individual fears to be exposed to a vexing situation.
Group thinking is a negative practice that can underlie irrational decisions and nullify any process of innovating alternatives for contributing to the achievement of goals.
Answer:
4 years
Explanation:
Simple Interest is calculated using the formula below
I= P x r x t
Where I = Interest
p= principal
r= interest rate
t= time in years
In this case
I=81
p=450
r=4.5 % or 0.045
t=???
Therefore;
81= 450 x 0.045 x t
81=20.25t
t=81/20.25
t=4
It will take four years
