Chapter 7 #42 The accounting department at Weston Materials, Inc., a national manufacturer of unattached garages, reports that it takes two construction workers a mean of 32 hours and a standard deviation of 2 hours to erect the Red Barn model. Assume the assembly times follow the normal distribution. a. Determine the z values for 29 and 34 hours. What percent of the garages take between 32 hours and 34 hours to erect? z(29) = (29-32)/2 = -3/2 z(34) = (34-32)/2 = 1 z(32) = 0 P(32 < x <

A good scientific research requires explicit regularization, systemization and coordination of the process of observation, recording and analysis (Ghauri and Gronhang, 2005). Appraising research studies is important because it helps to find out if the research methods and results are valid enough to obtain important information (Fowkes and Fulton, 1991). Some criteria proposed by Lincoln and Guba (1985) used to assess the trustworthiness of qualitative research are credibility, transferability and

Methods Participants The participants included 42 students at the University of Kansas that agreed to individually completing the survey that was sent to them via social media sources such as GroupMe, Snapchat, and over text. 29 (69.05%) of the participants were female, 12 (28.57%) were male, and 1 chose to not specify. The participants ranged in age from 17-25 years old. When asked about geographical climate, 17 (41.46%) were from a rural/small town, 21 (51.22%) were from the suburbs, and 3 (7.32%)

target population for the survey is residents of Bakersfield. 4.2 Sample The sample will consist of a total of 100 male and 100 female residents from Bakersfield, who are aged between 18-65. It will be selected by using the stratified sample technique, which will involve dividing residents into groups based on their gender and then using those groups to conduct our sampling. This will ensure that we are able to obtain an even sample of male and females and allow for determination of any difference

I lost 2 points My mistake was failing to notice that the stems should split at the last digit, meaning the first two digits are separated from the last digit by a stem. Also, each stem must be assigned an equal number of leaf digits. So, zero should be added to the front of the 9 for the score of 96. So, choice (b): 09, 10, 11, 12,13, and 14 is the correct answer, since the stems separate the first two digits from the last digit and include an appropriate range of 09-14, for the numbers from and

Data analysis and presentation: Primary data: I asked all 60 people on whom I did my survey that did they complete any Human resource management course. On those 41% people said they already did 1 course. 24.6% BBA students said that they did two courses. 11.5% people on them said that, they had completed more than 2 courses that mean they are doing major on HRM. Rest 23% people are saying that they did not do any HR course yet. When I asked those sixty BBA students about necessity of

Population Growth 5 Problem and solution essay. Have you ever thought what will happen with us in our nearest future? Is there will be better life than today? When I first saw headlines such as “Better life is coming” or “Future without problems, it’s true”, I was tempted to answer, “Yes”. However, these facts aren’t so widely reported in the newspaper and television. But the nearest future, in fact, is not as fluffy as it seems to be.

50Dose Gender Affect Memory? Introduction: I believe that many other students like me that would like to believe that if a student got a good memory then his or her college life will be much easier.
