QUESTION 1

A major department store chain is interested in estimating the average amount its credit card customers spent on their first visit to the chain’s new store in the mall. Fifteen credit card accounts were randomly sampled from the normally distributed population and analyzed with the following results:  = $50.50.  The population variance is 400. A 95% confidence interval for the average amount the credit card customers spent on their first visit to the chain’s new store in the mall is:

  1. $50.50 ± $9.09.
  2. $50.50 ± $10.12.
  3. $50.50 ± $11.08.
  4. None of these choices.

QUESTION 2

A survey of an urban university showed that 750 of 1100 students sampled attended a home football game during the season. Using the 99% level of confidence, what is the confidence interval for the proportion of students attending a football game?

[0.767, 0.814]

[0.6550, 0.7050]

[0.6456, 0.7179

[0.6795, 0.6805]

QUESTION 3

The 95% Confidence Interval for the weights (in pounds) of a special type of rock has found to be 4.3, 8.46. What will be the margin of error? (Hint: Sample mean +/- margin of error = confidence interval)

QUESTION 4

In a large city, the average number of lawn mowings during summer is normally distributed with mean μ and standard deviation σ = 9.3. If I want the margin of error for a 90% confidence interval to be ±3, I should select a simple random sample of size (4 decimal points) 

QUESTION 5

In a large city, the average number of lawn mowings during summer is normally distributed with mean μ and standard deviation σ = 11.5. If I want the margin of error for a 99% confidence interval to be ±4, I should select a simple random sample of size (4 decimal points) 

QUESTION 6

The standard error of the mean for a sample of size 132 is 25. In order to cut the standard error of the mean in half (to 12.5) we must select a sample size of  …?

QUESTION 7

21 credit card holders are selected at random. For each, their current credit card balance is recorded. The average for these 21 people is = $600. Assume that the current balance of all credit card holders follows a normal distribution with unknown mean μ, and that a 85.3% confidence interval for μ is found to be $600 ± 34. Find the standard deviation σ of the population?

Write a 5 page essay on Hacking the Accounting Information System.

One of the companies which got hacked in recent times is Microsoft .inc. According to ( Smith,2012)“In simple terms computer hacking and cracking reflects, the intentional, unauthorized access to an organization’s computer system”. So the companies need to be alert and take considerable responsibility to secure its Accounting Information System (Thesis).Accounting Information System is a process which needs high security as many crucial and essential data are handled in it. Any business concern needs to take the responsibility to secure the confidential data so as to protect the company from hackers and unidentified encroachment. The business organisations have the responsibility to invent and install upgraded security system to ensure confidentiality and risk free environment for the company and its customers. Microsoft being the most prominent company in the world had been hacked few times .Thus the accounting information system along with the management

has undergone many challenges and losses. The company was hacked in 2012 by a group of Chinese hackers and in 2013 a java script was injected in the business system of the company. The Microsoft security response centre states the Microsoft Active Protection was a program that provide security for program that gives anti –hacking tool facility. However, the Microsoft did deny that hacking was not done by Chinese group but it was a “rookie mistake”. They said it was due to dodgy email attachment. So here we can see that hacking can be done even if the e- mails which are socially engineered to disrupt the business system.

As per (Peter,2013 ) “As reported by Face book and Apple, Microsoft can confirm that we also recently experienced a similar security intrusion,” wrote Matt Thomlinson, General Manager of Microsofts Trustworthy Computing Security. Unlike the New York Times and the Wall

dividual to intermittently clean the wet floor as to avoid the area from getting too slick. In my view the grocery store exercised ordinary care for the simple fact they could have sent a worker to the door to vocally caution customers of the wet floor and make certain that the floor was cleaned frequently keeping it safe. This would be considered slight negligence. There are essentially two defenses the grocery store could use in this situation. Contributory Negligence which is where the plaintiffs own fault aided to the injury. The plaintiff unmistakably saw the wet floor sign and selected to walk across the slippery
