Question 2) A random sample of 10 nursing student given anxiety test before and after some intervention. We want to know if we can conclude that the intervention was effective to decrease the anxiety level of nursing student? Let alpha be at 05. The higher score means more anxious. The following is the result of test: Either calculate by hand or use the following output to answer the questions.

a.What is the hypothesis testing for this test?

1.H0: Ud= 0 H1: Ud

2.H0: Ud= 0 H1: Udnot equal0

3.H0: Ud= 0 H1: Ud >0

b.What is the t statistics for this test?

1.2.50

2.-2.50

3.1.58

4.-1.71

c.What is your conclusion based on the P-value of the Sign Ranked test?

1.Since P value (.1387/2=.07) is not less than alpha (.05) we fail to reject null and cannot conclude that the intervention was effective to decrease the anxiety level of nursing students at alpha .05.

2.Since P value (.1387/2=.07) is not less than alpha (.05) we reject null and conclude that the intervention was effective to decrease the anxiety level of nursing students at alpha .05.

d.What type of parametric test you can use for this problem if you have larger sample?

1.One sample test

2.One sample proportion

3.One sample paired test or matched T-test

4, One sample variance
