...• A team member who does not submit his or her portion of an assignment When you are a part of a team it is important to understand that your actions, or lack of actions, affect the entire team. A team leader makes assignments for portions of a project to be completed in order for the entire project to be completed on time and ensure that one person on the team isn’t doing more than they can handle. When a member of the team does not do what they were assigned, the rest of the team has to pick up the slack and rush to complete the portion that the team member missed. This puts the rest of the team in a situation that could cause stress and extra work that they wouldn’t have had to deal with if the team member had done what they said they would do. In order to avoid this it is important for all team members to understand the importance of doing what they are assigned to do. • A team member who does not meet deadlines There are many things to consider when something goes wrong when you are a part of a team or group. The first thing I would do is make sure that the deadline was known and that the team member understood the deadline and what was supposed to be completed. If there was a misunderstanding then I would make sure that the rest of the team didn’t have the same misunderstanding about the deadlines and their importance. This situation is especially true for me and this assignment. I was late in submitting my portion and it has put team members in this exact scenario...

...1. A shoe manufacturer’s data show that the distribution of shoe size is normal with a mean of 11inches and SD 1.5 inches. * A manager of the company claims that 70% of the times shoe size will be between 8 and 12 inches. What do you think? In your deliverables, write a few lines about what you think of the manager’s claim and what would you advise him to do. (1 point) The probability of a size being below size 8 is .02275 and the probability of a show size being size 12 or below is .747507. The probability of a size being between size 8 and 12 is .724732 or 72.4732%. * How would you modify the manager’s claim if the distribution of shoe size was not normal? (1 point). I would change the claim to 75% and calculate the range using Chebychev’s Theorem. Using this theorem, 75% of the data should fall within 2 standard deviations of the mean, so the 75% of the time a shoe size would between size 8 and 14. * What is (are) size(s) of shoe for which the probability of occurrence is less than or equal to 5%? In your deliverables, report the size. Explain in a few lines how you came to your conclusion. For this, assume shoe size is normally distributed. (2 points). To calculate this we can calculate for 5% and 95% probability using Norm Inverse. This gives the number of 8.53272 and 13.46728. So a shoe size below 8.53272 or larger than 13.46728 has a probability of less than or equal to 5%. 2. Those who apply for admission to OSU’s graduate college have...

Three Trends in Nursing Practice

...understand current practice? Identify at least three trends in nursing practice demonstrated by the interactive timeline. How have these trends influenced your perspective of nursing practice? Nursing is a noble vocation that has been into practice from ages but not as a profession neither did anyone consider serving another without any reward or benefit. I remember the illustration of Good Samaritan, by Jesus Christ. Being born to Christian parents even the pioneer of Nursing, Florence Nightingale had the heart of Good Samaritan, and that was it. We always need one person to give a start. With great difficulties, against to her parents desires the great Florence Nightingale stood for the reason, her commission and desire. Before Florence Nightingale, Dorothea Lynde Dix tried to go an extra mile in improving the care for the mentally ill. Through the presentation site provided by GCU, we could understand the other persons who contributed much to humanity in the initial stages of nursing. From the beginning of nursing practice till now there have been great changes that took place in the due course of time. From the manual mode of nursing practice now we have advanced to the technical and technological nursing care in every areas of our work. Some of the nursing care activities are now being done by the aides. The advancement we have achieved in nursing care is the specialization of care and the progression of our profession to its height. Once there was a time when people......

Week Three Problems

...University of Phoenix Material Week Three Practice Problems Prepare a written response to the following questions. Chapter 4 11. List the five steps of hypothesis testing, and explain the procedure and logic of each. 1. “Restate the question as a research hypothesis and a null hypothesis about the populations”. One makes a research hypothesis about a predicted correspondence among populations. The research and the null hypothesis’ are opposites, meaning if one hypothesis is correct and true the other is not. 2. “Determine the characteristics of the comparison distribution”. This is important because the comparison distribution represents the population situation if the null hypothesis is factual. This is the main idea of hypothesis testing. 3. “Determine what the cutoff sample scores on the comparison distribution where the null hypothesis should be rejected”. This means determining a target against the results that will be compared or to what extreme the sample score would have to be for it to be too doubtful that they could get such an extreme score if the null hypothesis were true. Here the null hypothesis would be rejected if the point of the cutoff sample scores reaches or exceeds the sample score. If the null hypothesis is true the Z score is established at a score which would be improbable. 4. This step is to get the actual results for the sample. “Determine your sample’s score on the comparison distribution” . After one gets......

Do this practice problem by hand using a calculator. What is your conclusion regarding the research hypothesis? Remember to first decide whether this is a one- or two-tailed test. The conclusion reached is that this is a two tailed test showing there is no difference between the levels of significance in boys or girls raising their hands. 2.
