Assume that the population distributions of life expectancy (in years) of men and women are normal with equal variances. Two random samples, drawn independently from the populations, showed the following statistics.
Men: 
= 10, 
= 76, 
= 1
Women: 
= 10, 
= 83, 
= 4
Construct and interpret a 99% confidence interval for the true difference in average life expectancy of men and women.
