Compare X = production in February and Y = production in September, for the years 1981 to 1995 following our example below. Find 99% confidence intervals. First, assume that population variances are known and that X and Y are independent. Second, determine if the data gives support for the idea that X and Y may be independent. And lastly, assume the population variances are unknown and that X and Y are dependent.
