Question

A health psychologist hypothesizes wants to investigate white coat hypertension. White coat hypertension is when a patient grows anxious when a person with a white coat and stethoscope walks into the examination room. To investigate, the psychologist randomly selects patients in a hospital that have come in for various minor ailments. During this visit the doctor either wears a white coat or a (non-white) sport coat. The patients are then asked to come in the next week for a follow-up. At the follow-up, the doctor wears the opposite of what he wore during the first visit. Below are the systolic pressures of the patients at each visit. What can be concluded with α = 0.05?

white coat	sport coat
104 100 118 117 108 102 103 115 112 105	117 115 112 124 116 118 121 113 118 108

c) Obtain/compute the appropriate values to make a decision about H₀.
(Hint: Make sure to write down the null and alternative hypotheses to help solve the problem.)
critical value =  ; test statistic =
Decision: Reject H0 or Fail to reject H0

d) If appropriate, compute the CI. If not appropriate, input "na" for both spaces below.
[  ,  ]

e) Compute the corresponding effect size(s) and indicate magnitude(s).
If not appropriate, input and/or select "na" below.
d = _______ ; na trivial effect small effect medium effect large effect
r² = _______ ;   na trivial effect small effect medium effect large effect

f) Make an interpretation based on the results.

Patients are more significantly anxious with the doctor wearing a white coat

.Patients are more significantly anxious with the doctor wearing a sport coat.  

  Patients show no significant anxiety difference with the doctor wearing a white coat or sport coat.
