A. All of these influence type II error
B. Selection of test statistic
C.Sample size

2. If a health plan analyst wanted to determine if the readmissions rates for two hospitals were statistically different, which hypothesis test should be used?
A. One –sample Z-test for proportions
B. Chi square
C.Two-sample Z-test for proportions

3. A one-sample z-test for proportions may be used to:
A. Determine if a standard mortality rate is valid
B.Determine if the mortality rate at one hospital is higher than another
C. Determine if the mortality rate at one hospital is different from a standard

4. According to The Joint Commission in 2015, which of the following was one of the most common root causes of sentinel events in healthcare organizations?
A. Too few facilities with advanced information technology
B. Inadequate communication between care providers
C. Failure of process safeguards

5. What type of form is used by hospital caregivers to document potential or actual patient safety concerns?
A. Environmental assessment
B. Incident report
C. Check sheet

Answer 1

1)Selection of test statistics doesn't covers under type 2 error because type 2 error are based on failure to reject false null hypothesis

2) Two sample z proportion test can be used for all types of comparative studies.

3)A one- sample z test proportions are one used to test whether a particular parameter is different from the standard or from hypothesis.So it can determine if the mortality rate from one hospital is different from the standard.

4)Inadequate communication is one of the sentinel events faced by patient which was reported to joint commission

5) Incident report are one which is maintained to record any untoward events helping in potential problem prevention in future.
