The white stork (latin name: Ciconia ciconia) is a native of the
Netherlands. The poor thing experienced a decline of fortunes
during the postwar period. Today, the white stork has all but
disappeared from the Dutch landscape. During the same period,
the human birth rate of the Netherlands has also declined.
The following are real-life data on the average number of pairs of
storks and the human birth rate, over time.
Year
1961 1963 1965 1967
1969 1971 1973 1975
# of storks 46.2
33.1 32.0 19.3
19.1 5.0 6.0
9.0
Birth
rate 21.3
20.9 19.9 18.9
19.2 17.2 14.5 13.0
Determine if there is a significant association between the
decline in the human birth rate and the decline in the number of
storks over time.
