Question
Calculate the test statistic. (Use current year airfare previous year airfare. Round your answer to three decimal places.) Calculate the p-value. (Round your answer to four decimal places.) p-value Using a 0.05 level of significance, what is your conclusion? Reject Ho. We cannot conclude that there has been a significant increase in the mean domestic airfare for business travel for the one-year period. Do not reject Ho. We cannot conclude that there has been a significant increase in the mean domestic airfare for business travel for the one-year period. Do not reject Ho. We can conclude that there has been a significant increase in the mean domestic airfare for business travel for the one-year period. Reject Ho. We can conclude that there has been a significant increase in the mean domestic airfare for business travel for the one-year period. (b) What is the sample mean domestic airfare (in dollars) for business travel for each year? current $ previous $ (c) What is the percentage change in mean airfare for the one-year period? Percentage change is given as ((x, - x,)/x,)*100 where x, is in the initial value (in this case, the previous year). (Round your answer to one decimal place, do not include the % symbol in your answer.) %
