Independent random samples were selected from two quantitative populations, with sample sizes, means, and variances given. Construct a 95% confidence interval for the difference in the population means.

Then find a point estimate for the difference in the population means and calculate the margin of error.

Compare your results. Can you conclude that there is a difference in the two population means?
