It is generally accepted that patients grow anxious when a person with a white coat and stethoscope walks into an examining room; i.e., patients have white coat hypertension. A family practitioner is curious about this. To test this, the practitioner has colleagues from the practice randomly visit patients in a white coat or non-white sport coat, and measure their blood pressure. What can the practitioner conclude with an α of 0.01? Below are the systolic blood pressures of the patients.

a) What is the appropriate test statistic?
---Select--- na z-test One-Sample t-test Independent-Samples t-test Related-Samples t-test

b)
Condition 1:
---Select--- examining room blood pressure white coat hypertension white coat non-white coat
Condition 2:
---Select--- examining room blood pressure white coat hypertension white coat non-white coat

c) Compute the appropriate test statistic(s) to make a decision about H0.
(Hint: Make sure to write down the null and alternative hypotheses to help solve the problem.)
p-value =  ; Decision:  ---Select--- Reject H0 Fail to reject H0

d) Using the SPSS results, compute the corresponding effect size(s) and indicate magnitude(s).
If not appropriate, input and/or select "na" below.
d =  ;   ---Select--- na trivial effect small effect medium effect large effect
r2 =  ;   ---Select--- na trivial effect small effect medium effect large effect

e) Make an interpretation based on the results.

The systolic blood pressure for patients that where visited by a practitioner with a white coat was significantly higher from patients that were visited by a practitioner in a non-white sport coat.

The systolic blood pressure for patients that where visited by a practitioner with a white coat was significantly lower from patients that were visited by a practitioner in a non-white sport coat.

The systolic blood pressure for patients that where visited by a practitioner with a white coat did not significantly differ from patients that were visited by a practitioner in a non-white sport coat.

a) The appropriate test statistic is - Independent-Samples t-test

b) Condition 1 - white coat

Condition 2 - non-white coat

c)

d) effect size , large effect

e) Conclusion - The systolic blood pressure for patients that where visited by a practitioner with a white coat was significantly higher from patients that were visited by a practitioner in a non-white sport coat.
