You are working for Altria as a data analyst for the southwest region. You are specifically interested in if there is any difference in daily revenue from Marlboro products sold at Circle K stores in Arizona versus from those in California. You sample 35 Arizona Circle K stores and find they average daily Marlboro revenue of $348 with a standard deviation of $22. A sample of 50 California Circle K stores shows an average daily Marlboro revenue of $379 with a standard deviation of $25. Use a 5% significance level for any testing and assume the population variances are equal. Treat Arizona Circle K stores as population 1. Calculate the test statistic needed to test your claim.
