Length of Stay ~ Health insurers and federal government are both putting pressure on hospitals to shorten the average length of stay (LOS) of their patients. The average LOS for women is 4.5753 days according to Statistical Abstract of the United States: 2005.
A first study conducted on a random sample of 20 hospitals in Michigan had a mean LOS for women of 3.8532 days and a standard deviation of 1.1599 days.
A medical researcher wants to determine the sample size required to estimate the mean LOS for women in Michigan at 95% confidence with a margin of error of no more than 0.2524 using the following formula,
n = (t*sME)2.n = t*sME2.
Note: Numbers are randomized for each instance of this question. Use the numbers given above.
What is the required sample size? Give your answer as a whole number.
Homework Answers
Given,
SD = 1.1599
E = 0.2524
For 95% confidence and 19 degrees of freedom, critical t value = 2.093
Hence,
Sample size required
n= 93

A random sample of 500 measurements on the length of stay in hospitals had sample mean 7.3 days and sample standard deviation 3.3 days. A federal regulatory agency hypothesizes that the average length of stay is in excess of 7 days. Use α = 0.05. Using the rejection region from a test to determine whether the data supports the regulators claim, calculate β when μa = 7.4. (Round your answer to four decimal places.)

Directions What is a research proposal? The purpose of a research proposal is to identify and formulate questions that arise from nursing practice and to design a research project to study the identified problem. The goal of a research proposal is to present and justify a research idea you have and to present the practical ways in which you think this research should be conducted. Research proposals contain extensive literature reviews and must provide persuasive evidence that there is a...
