Suppose that you calculate the sample correlation between
long-term money supply growth and long-term inflation in ten (n =
10) industrialized countries to be 0.78 (? = .78). Test the null
hypotheses ?0, that the true correlation in the
population is 0 (? = 0) against the alternative hypothesis, ??,
that the correlation in the population is different from 0 (? ā 0)
at a 5% level of significance.
