In a study at a large hospital the researcher wants to assure that male nurses are adequately represented. At this hospital 5% of the nurses are male. The researcher separates the nurses into female and male hats. He draws 95 female names and 5 male names. This is an example of:

Select one:

a. Simple random sampling.

b. Stratified random sampling.

c. Multistage random sampling.

d. Cluster sampling.

Expert Solution

Solution: The sampling procedure used here is the Stratified random sampling.

Therefore, the correct option is b. Stratified random sampling.

Explanation:

Simple random sampling is the one in which each and every unit of the population has an equal chance of being included in the sample. The researcher randomly selects the sample using various techniques like random number table, lottery method etc.

Stratified sampling: In this type of sampling, the investigator first divides the entire population into homogeneous groups (usually referred as strata’s) based on certain characteristics and then the investigator randomly selects a sample from each of these strata’s.

Multistage random sampling: In this type of sampling, the population is divided into various stages to take a random sample.

Cluster sampling: In cluster sampling, the investigator divides the population into several clusters and then randomly selects some of the clusters. All the members of the chosen clusters are studied.

Therefore, in the given example, a stratified random sampling procedure is used.

One of the local hospitals wants to assure that they have enough nurses for incoming patients needing assistance, especially in the emergency room. To insure there are enough nurses on duty, but not an overage which would waste hospital resources, the following data regarding the number of patients entering the hospital over the last several weeks has been gathered. The data does not include weekend patient traffic, as the hospital has previously done a similar study and staffed weekends appropriately....

As a hospital administrator of a large hospital, you are concerned with the absenteeism among nurses' aides. The issue has been raised by registered nurses, who feel they often have to perform work normally done by their aides. To get the facts, absenteeism data were gathered for the last three weeks, which is considered a representative period for future conditions. After taking random samples of 60 personnel files each day, the following data were produced Day Aides Absent Day...

You are the manager of a clinical lab at large-sized hospital. Physicians and nurses are concerned about the early morning turnaround time for lab tests. It appears the samples are collected on the 6:00 A.M round. Physicians begin their patient rounds at 7:30 A.M and prefer to see the lab tests results at the time they see the patient so they can make decisions with regards to patient treatment . 1. What is the best method to address this problem?...

In a large hospital, a nursing director selected a random sample of 30 registered nurses and found that the mean of their ages was 30.2. The population standard deviation for the ages is 5.6. She selected a random sample of 40 nursing assistants and found the mean of their ages was 31.7. The population standard deviation of the ages for the assistants is 4.3. Find the 99% confidence interval of the differences in the ages.

A medical researcher wants to determine if the average hospital stay after a certain procedure is less than 11.87 days. The hypotheses for this scenario are as follows: Null Hypothesis: μ ≥ 11.87, Alternative Hypothesis: μ < 11.87. If the researcher randomly samples 25 patients that underwent the procedure and determines their average hospital stay was 10.6 days with a standard deviation of 6.724 days, what is the test statistic and p-value of this test? Question 10 options: 1) Test...
