The domestic airfare for business travel for the current year and the preVious year was reported. A sample of 12 flights with their domestic airfares shown for both years is contained in the Excel Online file below. Construct a spreadsheet to answer the following questions. Open spreadsheet a. Formulate the hypotheses and test for a significant increase in the mean domestic airfare for business travel for the one-year period. Ho : µ1 – 42 Ha : µ1 – H2 What are the t-value, degrees of freedom, and p-value t-value (to 4 decimals) Degrees of freedom p-value (to 4 decimals) Using a .05 level of significance, what is your conclusion? We cannot conclude O that there has been a significance increase in business travel airfares over the one-year period.
