QUESTION 27
A researcher wants to see how men and
women differ in their reaction to a headache
medicine with respect to drowsiness. In
testing the hypotheses
•H:P1-P2<0.10 ,
the following statistics were obtained:
and x-115, where and , represent
the number of patients in the two samples
n3 = 400, x1=208, nz=250
X2
(men vs. women) who reported to have
drowsiness as a result of taking headache
medicine. What conclusion can we draw at
the 10% significance level?
The critical value is:
A. 1.96
B. 1.28
C.-1.28
D. -1.96.
