Explanation:
Answer: The minimum number of students you need if you want the margin of error to be 5% IS 278.
Explanation:
Cochran’s Sample Size Formula gives the minimum number of students as 
Where:
e is the desired level of precision (i.e. the margin of error),
p is the (estimated) proportion of the population which has the attribute in question and q is 1 – p.
The z-value for 95% confidence interval is found to be 1.96 in a Z table.
Assuming that half of the teenagers favor the elimination of a curfew: this gives us maximum variability. So p = 0.5 and q=0.5.
Then 
Rounding up, 
But considering that 1000 is a small population, we can modify the sample size we calculated above formula by using this equation:
Where s is the adjusted sample size, n is the original sample size we calculated and N is the population size.
Answer:
$71,428.57
Explanation:
we can use the perpetuity formula to solve this question:
present value = future cash flow / (discount rate - g)
- future cash flow = $10,000
- discount rate = 6%
- g = growth rate = -8%
present value = $10,000 / (6% - - 8%) = $10,000 / 14% = $71,428.57
Answer:
Latoya is responsible for her company’s human resource information system. She wants to expand the system’s usefulness and is preparing a recommendation to add data-mining applications. What does data mining involve?
a) analyzing large amounts of data, such as employee pay and performance
Explanation:
An information system is a combination of components that work collectively in the storage, transfer and processing of data. Information systems have various features including data mining which is a major component. Data mining can be defined as the process which data input is converted into useful information or output. In a company situation, there is usually large blocks of data. Going through these data blocks manually can be very tedious and time-consuming , thus costly. In most organizations however, they utilize data mining to break data down into simpler information that can be understood in a short time.
Data mining works by going through large data blocks and extracting relevant trends and patterns in them. Data mining has a number of uses, namely; detection of fraud, risk management of credit, and filtering opinion of users. The steps involved include: collection of data, then the data is loaded and stored in organizational servers, then analysts organize the data, then the data is processed using a software and finally the end result is presented in an easy to understand format.
In our case, Latoya is the company's human resource information system manager, thus her data-mining will probably involve analyzing large amounts of data, such as employee pay and performance.
