Explanation / Answer

1. When investigators compared nurses in magnet and non-magnet hospitals, which variables do you think were compared using the t-test? All that apply.

-Work schedule Index variables
-Physical demands
-Psychological demands
-Nursing practive environment variables

Answer:

All the variables describe above such as work schedule index variables, physical demands, psychological demands and nursing practice environment variables were compared by using the t test. In the work schedule index variables, work hours per day and work hours per week are compared for the nurses working in magnet and non-magnet hospitals. Also, different variables related to the nursing practice environment were compared by using t test.

2. What is the null hypothesis with respect to physical demands and magnet status?

Answer:

The null hypothesis is given as below:

Null hypothesis: H0: There is no any significant difference in the average physical demands coefficient for the nurses working in magnet hospitals and non-magnet hospitals.

H0: µ1 = µ2

3. What is the alternative hypothesis with respect to physical demands and magnet status?

Answer:

The Alternative hypothesis is given as below:

Alternative hypothesis: Ha: There is a significant difference in the average physical demands coefficient for the nurses working in magnet hospitals and non-magnet hospitals.

H0: µ1 µ2

4. What type of statistical test would have been most appropriate to test the association between physical demands and hospital magnet status?

Answer:

In this case, we use the parametric test such as t test for testing the association between the physical demands and hospital magnet status. The selection of the proper test is depends on the given assumptions and available information or data.

5. Interpret the results for physical demands. What data did you use to base your results?

Answer:

For the physical demands, the t test statistic is given as 2.140 with the p-value as 0.034. The p-value is less than the alpha value or level of significance 0.05, so we reject the null hypothesis that there is no any significant difference in the average physical demands coefficient for the nurses working in magnet hospitals and non-magnet hospitals. This means we conclude that there is sufficient evidence that there is a significant difference in the average physical demands coefficient for the nurses working in magnet hospitals and non-magnet hospitals. We use the data for the test statistic and p-value in the given table to base above results.
