Quality Associates Essay Example for Free

Quality Associates Essay Quality Associates, a consulting firm, advises its clients about sampling and statistical procedures that can be used to control their manufacturing processes. In particular application, a client gave Quality Associates a sample of 800 observations taken during a time in which that client’s process was operating satisfactorily. The sample standard deviation for these data was 0.21; hence with so much data, the population standard deviation was assumed to be 0.21. Quality Associates then suggested that random samples of size 30 be taken periodically to monitor the process on an ongoing basis. By analyzing news samples, the client could quickly learn whether the process was operation satisfactorily. When the process was not operation satisfactorily, corrective action could be taken to eliminate the problem. The design specification indicated the mean for the process should be 12. The hypothesis test suggested by Quality Associates follows. : : Corrective action will be taken any time is rejected. The dataset â€Å"Quality.sav† contains each of four samples, each of size 30, collected at hourly intervals during the first day of operation of the new statistical control procedure. Managerial report 1. Conduct a hypothesis test for each sample at the 0.01 level of significance and determine what action, if any, should be taken. Provide the test statistic and the p-value for each test. 2. Compute the standard deviation for each of the four samples. Does the assumption of 0.21 for the standard deviation appear reasonable? 3. Compute limits for the sample mean Ì… around such that, as long as, a new sample mean is within those limits, the process will be considered to be operation satisfactorily. If Ì… exceeds the upper limit or if below lower limit, corrective action will be taken. These limits are referred to as upper and lower control limits for quality purposes. 4. Discuss the implications of changing the level of significance (ÃŽ ±) to a larger value. What mistakes or error (type I or type II error) could increase if the level of significance is increased?

Book Review of Goosebumps Stay Out of the Basement :: essays research papers

I have read a book called Goosebumps Stay Out Of the Basement. It was an intresting book and it was a little confusing because the characters jumped around in the story. Also, when you were reading the story you feel like you missed out on a part and you just have to go along with the story and find things that happen in the past. The author of this book is R. L.Stine. He has written many books in the Goosebumps series and they all hold there scariness in many ways.They are a series of scary and supernatural made up stories.These are some books that he has written:The Abdominal Snowman of Pasadena,Attack of the Mutant,Bad Hare Day,The Barking Ghost,The Cuckcoo clock of Doom,The Curse of the Mummy's tomb,Deep Trouble,Egg Monsters From Mars and many more.The genre of this book is fiction because it has ficticious characters that are not real and are not true including monsters. I chose this book because it looked very intresting and I was very drawn to this book when I saw it. By just looking at the picture on the front cover was very intresting and creepy and I like those things. In the beginning of the story, Margaret and Casey are talking about how there dad a scientist is acting very weird. They notice that he has been down there in the basement with his plants and weird machines for a long time. He had hardly ever come up from the basement to get fresh air. When he did come up he would'nt even want to catch a frisbee. He also did not spend two minutes with either of them when he did come up. They also notice his skin getting a pale green and speaks in very bad manners that the kids have never heard before. Then in the middle of the book they find out some very uncomfortable things about there dad and they feel as if he is not there dads anymore. When the two kids had gone down into the the basement [which there dad had yelled at them and told them not to go down there] they found a whole bunch of weird plants and the air was all mooshy and thick. They kinda noticed that one of the plants were breathing and it was true because when they went near the pla nt you could actually hear it breathing.

Middle schools Essay

There are some types of conditioning that are employed in middle schools and high school settings. Take for example when the teachers enter the classroom, students are â€Å"conditioned† to react in certain ways. Thus, this depends on what they are used to and how teachers will treat such type of behaviors. The initial reaction of the students is referred to as the ‘baseline behavior’ (Honolulu Zoo Organization, 2009). Before any type of conditioning is applied, this behavior should be observed and recorded. In a classical conditioning, there is a large dependence on the association of a stimulus to a response and has involuntary reactions (Comparison of Classical and Operant Conditioning, 2009). In a classroom setting, classical conditioning can also be applied. Say, students love their music class and that they love to sing. Thus, before each music class, the teacher would play a song. Thus, when the students hear the music, they may start to sing or hum to the tune of the music. This increases their awareness that music class will be next. Then, shaping is applied where a series of actions are equated to a series of reactions. This defines the difference between the baseline and terminal behavior. For an operant conditioning, the most notable feature is the ‘reinforcement’ and that the reactions are voluntary (Comparison of Classical and Operant Conditioning, 2009). Say when one teacher enters the classroom, the students to stand up and greet by applause. This may be construed by the teacher as the good behavior and, thus, the teacher may give a reward for each student when the students stand and applaud. Say, the reward is a candy bar, which now serves as the positive reinforcement. Consequently, without the â€Å"stand and applaud response,† the candy bar is withheld and students are forced to stand, thus a negative reinforcement. When this is done in an every â€Å"stand and applaud reaction† response basis, thus, continuous reinforcement is applied. Within the shaping, reinforcements may vary. The reinforcement may be done in random, meaning candy bar is not given every time the stand and applaud reaction is done by student, which is called variable reinforcement. If in case the teacher gives more candy bars for a louder applause, then this is now referred to as the selective reinforcement with the aim of increasing performance. Another schedule of reinforcement is the bonus wherein the students may receive more candy bars than the usual as a surprise. The terminal behavior is the behavior after the ‘shaping’ is applied. In this example, the students’ action of standing and applauding every time the same teacher enters the classroom is the terminal behavior after the shaping including the reinforcement. Negative reinforcement is if students fail to stand and applaud or if they just sit instead of stand, the candy bar is then withheld, thus, the students will go back to the stand and applaud response for the candy bar. Negative reinforcement then pushes that the students do something for their benefit. Punishment, on the other hand, is when the students stand and applaud and then they are all sent to the principal’s office, which weakens the ‘enthusiasm’ for stand and applause behavior. Then, if the candy bar is removed after the ‘stand and applaud reaction’, thus, the reaction is no longer encouraged and this is then called the extinction. Reward is a very powerful tool for students and the proper use of it should be understood before it is utilized by the members of the academe. In the same manner, rewards can make or break students’ habits and behavior. This could be dangerous since there is a tendency of students lacking the initiative to work without the reward. This may keep students from doing their best since there is no visible gain for better performance in school. On the other hand, this may also be very helpful in stirring movements for students towards positive actions and better performance. This may be an extra boost on their determination to achieve more in their activities. Reference: Comparison of Classical and Operant Conditioning. (2009). The McGraw-Hill Companies.

Considering that I am in the stage of improving my educational background as a strategy on strengthening my career development is one of the best stages in my life.

Children, especially women, usually move out from their parents authority only after they get married.
