Question

A doctor hypothesizes that females have higher systolic blood pressure than males. The doctor obtains the blood pressure from a sample of patients during their annual check-up. Below is the systolic blood pressure for the sample. What can be concluded with α = 0.05?

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

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--- doctor females sex systolic blood pressure males
Condition 2:
---Select--- doctor females sex systolic blood pressure males

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:  ---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.

The males have significantly higher systolic blood pressure than the females.

The females have significantly higher systolic blood pressure than the males.     

There is no significant systolic blood pressure difference among sexes.
