Suppose a correlation between the IQs of 714 pairs of adoptive siblings and biological offspring, reared together, is 0.32.

a)Using appropriate symbols, how do I find the null hypothesis for the correlation coefficient.

b)How do I find/what is the observed (calculated) value of the inferential statistic for the correlation coefficient?

c)Based on a two-tailed test, what is the probability of obtaining this inferential statistic?

d)What is the result if I were to compare the observed and critical values of the inferential statistic with = .05.

e)What can I conclude about the null hypothesis at = .05?
