Suppose 50 married couples are asked to provide their ages. For all couples, the husband is exactly 2 years older than his wife. For example, a 50-year-old husband has a wife who is 48 years old. What is the best estimate of the correlation coefficient between the ages of husbands and their wives?

▸ The correlation coefficient between the ages of husbands and wives is equal to 0.

▸ The correlation coefficient between the ages of husbands and wives is equal to -1.

▸ The correlation coefficient between the ages of husbands and wives is equal to 1.

▸ No conclusions can be drawn without seeing a scatterplot of the data.
