Application:
1. Find the area under the standard normal curve between z = 0 and z = 1.65.
Answer: The value 1.65 may be written as 1.6 to .05, and by locating 1.6 under the column labeled z in the standard normal distribution table (Appendix 2) and then moving to the right of 1.6 until you come under the .05 column, you find the area .450 . This area is expressed as
2. Find the area under the standard normal curve between z = -1.65 and z = 0.
Answer: The area may be represented as . Since the normal curve is symmetric, then
3. Find the area under the standard normal curve between z = -1.65 and z = 1.96.
Answer: The area may be represented as. This may be broken down

Scores on the SAT Verbal Test in recent years follow approximately normal distribution with mean 505 and standard deviation 110. How high must the student score in order to place in the top 100% of all students taking the SAT?
Answer: Being in the top 100% implies having at least the 90th percentile. The entry in the standard normal distribution table that is closest to .9 is 0.3997 + 0.5. The value of z that corresponds to this is 1.28. Hence,
Exercises:
1. An important measure of the performance of a locomotive is its adhesion, which is the locomotives pulling force as a multiple of its weight. The adhesion of a 440 horsepower diesel locomotive varies in actual use according to a normal distribution with mean = 0.37 and standard deviation = 0.04, a.) What proportion of adhesions measures higher than 0.40? b.) What proportion of adhesions is between 0.40 and 0.50?
Answer:
2. Use the standard normal distribution table to find the value of Z that satisfies the following conditions: a.) the point z with 25% of the observations falling to the left of it, b>0 the point z with 40% of the observations falling to the right of it.
Answer:
a. the closest value is
BU275 Assignment 2 Equations Question 1 A Station 1: Prep Inter-arrival time is the time between consecutive arrivals of the customers. Because the inter-arrival times are exponentially distributed, customers arrive at random times. The mean is 100 customers/ hours. This indicates that a customer arrives every 0.6 minutes.
1. Identify drives to which the databases and/or logs will be backed up, ensuring that there is enough disk space to accommodate the backups for the retention period that you choose. 2. Identify drive that will be used for data or log files. These will usually be on SAN storage and hence on a different drive from the operating system and SQL Server installations.
The pt WILLIAMSON, RICKY A wants to attend the unit 7354. I called the unit and they are completely full and was told they do not have a manager right now. The clinic said the pt can be put on a waiting list but unfortunately the pt has attended the unit 7354 and may have some compliance issues. Please confirm if the pt is denied of pt or if the pt can be put on the waiting list.
When deciding the server to be used for synchronizing its clock, a client should consider two main factors: 1. Reliability of the server The server should be highly reliable. It should be sending the correct time.
1. After placing about fifteen poker chips of one color in a pile near the row of six square blocks. I tell her that “Each block needs a chip as a partner. Can you take some chips so that there is the same amount to go with the blocks?” After telling her that she then assemble the blocks and poker pieces in pairs where each block has two poker pieces.
70-687 Scenario 1-1: Windows Enterprise would be the best option, but for this small business network I would think 8.1 Pro. Features within Windows 8.1 Pro allow an organization to centrally manage a network, including user profiles and computer settings, from a single server. Windows 8.1 pro also includes Hyper-V, Bitlocker, and Remote-Desktop hosting. Scenario 1-2:
6-1. Examples of organizations that could have information silos could be a local restaurant and a chain restaurant. Both probably have information silos if they have a database for each area of work. This could happen if each area doesn 't have a way to communicate their data to the others, which causes problems in the business system running smoothly. For the local store, an EAI would probably be the best because it is for smaller businesses and would disrupt business for a shorter period of time.
Sample questions for midterm 1. In a skewed distribution, which of the following values is most likely to be dragged toward the longer tail of the distribution? a) the mean b) the mode c) the median d) none of the above 2. Which of the following RFM codes represents a potentially very valuable customer who hasn’t bought recently and should be encouraged to order? a) 511 b) 111 c) 151 d) 115
Chapter two reviews probability and the normal distribution. Probability equals the number of events meeting the specified condition divided by the number of possibilities (Mirabella, p. 2-1, 2011). For example, my organization two primary products. Those products are orange postal bags and brown boxes. Forty percent of the volume consists of orange postal bags.
1. What is Test Package? Test package gives access to an indexed database of questions based on subject and topic. Based on the package you buy the access is limited by total number of questions. 2.
5. Public trials and executions serve as a deterance of deviant behaviors. These sanctions act as a way to set an example and for people to see what will happen to them if they do the same thing, These sanctions can also be seen as reinforcing boundaries. Although public executions and trials in “town square” are not as common in most countries today, the media is utilized to fulfil the same purpose. When there are high profile cases going on in the United States often tmes the full trial and sentancings are televised so that much of society can see what the repercussions are for defying a social norm.

In 1942, the SAT was used for all applicants. “In 1948, the SAT was becoming the basic college admission device for millions” (“A Brief History of the SAT”). 80% of schools still require a standardized test score for acceptance (Blaf). However, this percentage is going down and as it does colleges will rely more a grades, which are more precise calculations of
