Central tendency and variability

  Use SAS to carry out these tasks: Use measures of central tendency and variability to create a descriptive analysis of the daily sales for each store. Create a 95% confidence interval for the average daily sales for each store (Store A and Store B) for the year. Choose a confidence level for your hypothesis tests. (Common confidence levels include 90%, 95%, and 99%, but you can choose a different level if you desire.) Conduct a test of hypothesis to determine whether Store A's average daily sales for the year significantly exceeded the break-even threshold of $4900. Conduct a test of hypothesis to determine whether Store B's average daily sales for the year significantly exceeded the break-even threshold of $4900. Conduct an additional test of hypothesis to determine whether Store A's average daily sales was significantly lower than Store B's average daily sales.
