4. A researcher is interested in testing the hypothesis that income is negatively related to family size. A random sample of 10 families was selected from the population of a large mid-western city. All families were assessed on both their per-family income and their numbers of children. Family Per-family income Number of children $190,000 $30,000 $19,000 $40,000 $23,000 $40,000 $25,000 $40,000 $28,000 $30,000 Since the income distribution was badly skewed, it was decided not to use the Pearson I. Calculate and report the appropriate correlation coefficient. Should Ho be rejected or accepted, alpha .05? Use APA format, with the exception of the p-value since it wasn't calculated
