Question 30
Transcribed Image Text:30. A researcher wants to know whether athletic women are more flexible than non-athletic
women. For this experiment, a woman who exercised vigorously at least four times per week
was considered "athletic". Flexibility is measured in inches on a sit & reach box. A researcher
tested his claim using the following summary statistics:
Non-athletic women
n = 30
F = 4.6 inches
s=0.8 inches
Athletic women
m = 50
5.0 inches
s=1.4 inches
Assume that all conditions for testing have been met. t = 1.626; p = 0.057; At the 1%
significance level, state your decision regarding the null hypothesis and your
conclusion about the original claim.
A) Fail to reject the null hypothesis; there is not strong enough evidence to suggest
that athletic women are more flexible, on average, than non-athletic women.
B) Reject the null hypothesis; there is strong evidence to suggest that non-athletic
women are more flexible, on average, than athletic women.
C) Fail to reject the null hypothesis; there is strong evidence to suggest that non-
athletic women are more flexible, on average, than athletic women.
D)Reject the null hypothesis; there is strong evidence to suggest that athletic
women are more flexible, on average, than non-athletic women.
