equal population variances. Construct a 90% confidence interval to
estimate the difference in population means. Assume the population
variances are equal and that the populations are normally
distributed.

Use the t-distribution to find a confidence interval
for a difference in means μ1-μ2 given the relevant sample results.
Give the best estimate for μ1-μ2, the margin of error, and the
confidence interval. Assume the results come from random samples
from populations that are approximately normally distributed.
