Question

Application Exercise:
A physician hypothesizes that males have higher systolic blood pressure than females. The physician obtains a sample of patients and measures their blood pressures during their regular check-up. Below is the systolic blood pressure for the sample. What can the physician conclude with α = 0.01?

male	female
106 119 98 105 100 132 109 113 98 105	137 115 119 115 127 122 131 124 111 136

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--- male female systolic blood pressure physician sex
Condition 2:
---Select--- male female systolic blood pressure physician sex

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.)
critical value =  ; test statistic =  
Decision:  ---Select--- Reject H0 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 =  ;  ---Select--- na trivial effect small effect medium effect large effect
r² =  ;  ---Select--- na trivial effect small effect medium effect large effect

f) Make an interpretation based on the results.

Males have significantly higher systolic blood pressure than females.Females have significantly higher systolic blood pressure than males.    Males and females do not have significantly different systolic blood pressure.
