Week 5 problems Name: Show your work to receive partial credit. PLEASE DO NOT USE ANY RED FONTS #1 Find the standard error of the mean for each sampling situation (assuming a normal population). What happens to the standard error each time you quadruple the sample size? a. σ = 36‚ n = 9 36 √9=12 b. σ = 36‚ n = 36 36 √36=6 c. σ = 36‚ n = 144 =3 formula SE= σ √n #2.

there were many positive and negative effects of each step. The key elements of Patient Safety Initiative were followed by three steps‚ the first step was presentations that she conducted to the hospital staff about the national research and medical errors. The second step was focus groups that focused on the patient safety issues at Children’s Hospitals and Clinics. The third step was to make the initiative more strategic by developing it. Morath wanted to create a culture where she had the concept

Transportation Survey Sample Calculation The confidence interval (also called margin of error) is the plus-or-minus figure usually reported in newspaper or television opinion poll results. For example‚ if you use a confidence interval of 4 and 47% percent of your sample picks an answer you can be "sure" that if you had asked the question of the entire relevant population between 43% (47-4) and 51% (47+4) would have picked that answer. The confidence level tells you how sure you can be. It is

Case Study #2- Medication Error 1. Define “overdose.” What are some symptoms of overdose and statistics? Contrast accidental and intentional overdoses. An overdose is when a dangerous dosage of a drug is ingested. Fluctuation vital signs‚ exhaustion‚ dizziness‚ and chest‚ hear‚ and lung pain are all symptoms of overdose. Prescription drugs are the largest cause of deaths from overdose. In 2005‚ out of the 22‚400 overdoses‚ 38.2% were the result of pain killers. Intentional overdose is the misuse

Prevalence of Medical Errors Medical errors are currently the 3rd leading cause of death in the United States. These errors happen around us everyday even when we may not notice‚ which has made medical errors the silent killer in medicine. In todays society we must use manpower and our resources to deliver safer care as well as lead with accountability and help our providers to become more engaged. Every healthcare professional should listen to their patients and document care like we would want

respondents or elements to be sampled. However‚ by limiting the sample to only this group‚ the projections may not be reliable if the sample characteristics may vary from one another. As with all non probability sampling methods‚ the degree and direction of error in judgmental sampling cannot be measured and statistics that measure the precision of the estimates cannot be

Correcting Error Reporting Systems HA 255-01 April 5‚ 2011 2 A sophisticated continuous quality improvement process should involve the clinical employees as well as the senior medical staff. “Leading an organization refers to an individual’s ability to galvanize resources and motivate employees to work collectively to further organizational goals‚ which goes beyond simply controlling day-to-day operations.” (O’Connor‚ 2009) Continuous quality improvement cannot function properly

Medication errors are made time and time again by health care professionals all around the world. Although these errors are accidental they can be life-threatening. There are several types of medication errors that can occur‚ such as prescribing errors‚ transcription errors‚ dispensing errors‚ administration errors‚ and monitoring errors (Clayton and Willihnganz‚ p. 73). In this reading‚ it will specifically talk about an administration error and how it ended the life of a mother-of-four. Arsula

QTM Quiz 4 Set A 1. Out of a population of 60 people‚ the standard error comes to 1.65kg when calculating their average weight using sampling with replacement and 1.61 when using sampling without replacement. What is the sample size and standard deviation of the population? (4) N=60 With replacement‚ S.E. = Without replacement‚ S.E. = = 1.61 Thus‚ FPC = (N-n)/(N-1) = Thus‚ 60-n = 56.174 Thus‚ n = 3.8 or 4 approx. 2. When calculating the average income of the residents

We usually want to estimate some parameters of a population by a sample. These parameters estimates when we don’t observe whole population usually have some errors. Fortunately in probability sampling it is possible that we know how much our estimates are trustable or close to the parameter value from population by computing standard errors of estimates. This is not easily possible in non-probability sampling methods. Types of probability sampling methods Simple Random Sampling What is it
