A representative cross section of several thousand, Ask an Expert

Statistics

A representative cross section of several thousand husband-wife pairs is obtained. Looking at the ages, the average age of the husbands is 46 years and the average age of the wives is 43 years, with both groups having the same standard deviation of 13 years. The linear correlation coefficient between the ages of husband and wife is 0.95. The scatterplot is elliptical.

Using this information, roughly 68% of all men married to 63-year old women are between (A) and (B) years old, while roughly 95% of all men married to 63-year old women are between (C) and (D) years old. What are the values of A, B, C, and D?
