Confidence Intervals for Means

"Executives Whose Wives Stay at Home Earn More" was the headline for an article that appeared in the San Luis Obispo Telegram-Tribune (Oct. 14, 1994). To support this claim, the article presented data from a random sample of 231 married men who received MBA degrees in the late 1970s. The data are:

n Mean Salary    Standard Deviation 

Two-income family  140   $95,140   $15,000 

Sole source of income   91  $124,510   $18,000

Construct a 95% confidence interval for the difference in these means.
