Answer:
90% confidence interval estimate of the mean depth of all the frame in the entire consignment is between a lower limit of 105.419 mm and an upper limit of 106.581 mm.
Explanation:
Confidence interval of mean is given as mean +/- margin of error (E)
mean = 106 mm
sample sd = 3.5mm
n is sample size = 100
degree of freedom = n-1 = 100-1 = 99
confidence level (C) = 90% = 0.9
significance level = 1 - C = 1 - 0.9 = 0.1 = 10%
critical value (t) corresponding to 99 degrees of freedom and 10% significance level is 1.6602
E = t × sample sd/√n = 1.6602×3.5/√100 = 0.581 mm
Lower limit of mean = mean - E = 106 - 0.581 = 105.419 mm
Upper limit of mean = mean + E = 106 + 0.581 = 106.581 mm
90% confidence interval is (105.419 mm, 106.581 mm)
Answer:
Tax liability with proper financial planning can minimise
Explanation:
Financial planning is an important factor that can help to solve various financial problems. Proper financial planning helps to maintain a schedule to pay the debts/liabilities and enough cash to operate and handle daily operation. Without proper financial planning, liabilities can rise to an alarming level which usually leads to financial discrepancies and ultimately bankruptcy.
Answer:
Performing a horizontal Analysis
Explanation:
Particularly in the case of investigating fraud and error, horizontal changes are the most direct way of focusing on changes because rather than the vertical which looks at the change as a percentage of Sales or Total Assets, the horizontal looks at change in each item from period to period, and takes the change amount as a percentage of the initial year's amount. i.e (Year 2 amount - Year 1 amount) / Year 1 amount = % Change in item in consideration.
Ethics in a workplace is very important as it ensures that everyone is fair and accountable and treats every other person equally.
<h3>What is Ethics?</h3>
This refers to the proper way of doing things which ensures fairness and transparency.
With this in mind, we can see that in the absence of ethics, then business owners can engage in unethical practises which can lead to poor quality of goods in order to increase profit.
Please note that your question is incomplete so I gave you a general overview to help you get a better understanding of the concept.

Answer:
4-Firm Concentration ratio = 20%
Explanation:
Each firm has equal share
That means 100% share of the industry is divided equally among the 20 firm
Share of 1 firm = 100/20 = 5%
4-Firm Concentration ratio = Share of 1 firm * Number of firm
4-Firm Concentration ratio = 0.05 * 4
4-Firm Concentration ratio = 0.2
4-Firm Concentration ratio = 20%
