Based on your answer to Exercise 2.4.12, what sort of conclusion can you make and how are you determining this? 

A. We have strong evidence that the difference in ages for husbands and wives is greater than 0, on average (or husbands tend to be older than their wives), in the population because the p-value is less than 0.05. 

B. We have strong evidence that the difference in ages for all husbands and wives is greater than 0 (or all husbands are older than their wives) in the population because the p-value is less than 0.05. 

C. We do not have strong evidence that the difference in ages for husbands and wives is greater than 0, on average (or husbands tend to be older than their wives), in the population because the p-value is more than 0.05. 

D. We have strong evidence that the difference in ages for husbands and wives is greater than 0, on average (or husbands tend to be older than their wives), in the population because the p-value is more than 0.05.
