Answer:

The conditions for creating a confidence interval for the population proportion have been met.

Explanation:

There are the following conditions to build a confidence interval for a population proportion:

Sample of size n from a large population

Individuals chosen independent of one another

At least 15 failures and 15 sucesses in the sample.

In this problem, we have that:

Sample of 100 people

They are chosen at random at the market, so it means that the probability that an individual likes the new design is independent of any other individuals.

82 successes and 18 failures.

So yes, the conditions for creating a confidence interval for the population proportion have been met.

Answer:

If the representative interviewed 100 people at a certain supermarket, and 82 people indicated that they liked the new design,  the conditions for creating a confidence interval for the population proportion NOT been met because:

  1. the sample was from one source- supermarket.
  2. The number sampled (100 people) in comparison with the population of people in the state is negligible.

Explanation:

When constructing confidence intervals the assumptions and conditions of the central limit theorem must be met in order to use the normal model.

Randomization Condition: The data must be sampled randomly. Is one of the good sampling methodologies discussed in the Sampling and Data chapter being used?

Independence Assumption: The sample values must be independent of each other. This means that the occurrence of one event has no influence on the next event. Usually, if we know that people or items were selected randomly we can assume that the independence assumption is met.

10% Condition: When the sample is drawn without replacement (usually the case), the sample size, n, should be no more than 10% of the population.

Sample Size Condition: The sample size must be sufficiently large.

podryga [215]

Answer:

Explanation:

Calculation for the amount of G's 2022 salaries expense related to 2021 vacation time

First step is to find the Total salary expenses

G's employees earned average of $720 per week

Total vacation week in 2021 were not taken 550 week

Hence,

Total salary expense of G corporation = $720 per week × 550

Total salary expenses = $396,000

Second step is to calculate the salaries expense amount related to 2021 vacation time

Using this formula

Salaries Expense of G's 2022 = Total salary expenses × Wage rate

Let plug in the formula

Salaries Expense of G's 2022 = $396,000 × 7%

Salaries Expense of G's 2022

The amount of G's 2022 salaries expense = $27,720

Therefore the amount of G's 2022 salaries expense related to 2021 vacation time will be $27,720

Which file should you edit to limit the amount of concurrent logins for a specific user? (tip: enter the full path to the file.
saul85 [17]

Use /etc/security/limits.conf file to limit amount of concurrent logins for a specific user.

Use the /etc/security/limits.conf record to restrict aid use for all packages. That is from the pam_limits module of the Plugable Authentication Modules (PAM) module set. Entries in /etc/security/limits.conf comprise the subsequent: Entity type limit value.

A pluggable authentication module (PAM) is a mechanism to combine multiple low-level authentication schemes right into an excessive-stage Application programming interface (API). PAM allows applications that depend on authentication to be written independently of the underlying authentication scheme.

A module is a software program component or a part of an application that includes one or greater routines. One or more independently developed modules make up an application. A company-level software application may contain numerous one-of-a-kind modules, and each module serves unique and separate business operations.

Which of the following BEST describes a company's proper liquidity management?
Naddika [18.5K]

Answer:

A. Liquidity management is a balancing act, managers try to find liquidity levels that are neither too high not too low.

Explanation:

Maintaining proper liquidity is an important financial objective of management. Proper liquidity management demands that an entity should be able to meet his short term financial obligation and making sure that liquid assets of the entity are not idle. In order to achieve this, the best way to go is to maintain a level that is neither too high and not too low. Not too high means the entity is not holding too much cash or liquid assets than it currently need to meet its short term financial obligation.

For example, not keeping too much cash in current account but investing them in interest-earning investment assets.

Not too low means the cash or liquid assets held by an entity should not less than the amount needed to meet its short term financial obligation. For example, making sure that the entity has enough cash or readily convertible liquid assets that can be used to pay vendors, rent, interest and meet other short term financial obligation.

Option B is false because keeping too much does not help to maximize short term earnings which is a feature of proper liquidity management. Option C is wrong because there is no guideline to support that deferring coupon payment won`t attract payment and this does not connote proper liquidity management.

Option D is obviously false and does not describe proper liquidity management.
