Question

Refer to the tab titled "ED Satisfaction" for data required to solve this problem. You are looking at results of patient satisfaction from 2 different hospitals in your healthcare system related to patient experience in the Emergency Department (ED). One hundred patients from each hospital took a survey related to their satisfaction after being treated in the ED. The survey results were calculated on a scale from 0 to 10, with 10 indicating complete satisfaction. Hospitals are titled Hospital A and Hospital B. You want to know if patient satisfaction in the ED was the same or different based on the hospital.

1. What is your null hypothesis (H0) for this research topic? (Select either A or B from below.)

A. ED patient satisfaction is dependent on which hospital treatment was recieved from.

B. There is no difference in patient satisfaction related to the ED experience in Hospital A or Hospital B.

Calculate the mean of the patient satisfaction score for each hospital.

A. ______ Hospital A patient satisfaction

B. ______ Hospital B patient satisfaction

. Perform the appropriate statistical test to test for significance between the the two groups. Note, you can use the "data analysis toolpak" to get your result. Based on your results:

A. What p-value did you find and is this significant?

B.   Would you accept or reject the null hypothesis?

Explanation / Answer

1.

OPTION B: B. There is no difference in patient satisfaction related to the ED experience in Hospital A or Hospital B. [ANSWER, B]

***********************************

2.

Using the results in data analysis, the means are

xA = 5.39 [ANSWER]  
xB = 6.541 [ANSWER]

********************************

3.

Consider:

Using the two tailed P value,

Pvalue = 0.003660786 [ANSWER, P VALUE]

*********

As this is a very small P value, we reject the null hypothesis.

There is significant difference in patient satisfaction related to the ED experience in Hospital A or Hospital B. [CONCLUSION]
