In a cohort study, the
occurrence of infertility was recorded for smokers and non-smokers in the
reproductive age group, over a decade. The difference in incidences between
the 2 groups was reported to be significant at the p > 0.05 level. Which is
the most appropriate interpretation that can be made from the results of this
study?
a) The null
hypothesis can be rejected; results may have occurred by chance up to 5% of
the time
b) A
significant difference between the 2 groups may occur 5% of the time or less
c) The null
hypothesis may be accepted as the difference between the 2 groups is only 5%
of the time
d) The
alternate hypothesis may be rejected
e) A causal
relationship between exposure and outcome may be established at significance
level 0.05
