This test was conducted in one day. The subjects are individuals from my office. I set up the test in a vacant office. The water was served at room temperature in non-descript Styrofoam cups.

I need help creating a null and alternative hypothesis. I also need help analyzing and calculating the data. This analysis should include tables and charts where necessary. The use of the Chi test is encouraged. All other analyses should be shown in an Excel file, (i.e., contingency table, a problem using confidence level and lower tail or two tail test).
