(a)Formulate the hypotheses and test for a significant increase in the mean domestic airfare for business travel for theone-yearperiod.

H₀:_d< 0

H_a:_d= 0

H₀:_d0

H_a:_d< 0

H_a:_d= 0

Calculate the test statistic. (Use current year airfareprevious year airfare. Round your answer to three decimal places.)Calculate thep-value. (Round your answer to four decimal places.)p-value = Using a 0.05 level of significance, what is your conclusion?Do not rejectH₀. We can conclude that there has been a significant increase in the mean domestic airfare for business travel for the one-year period.RejectH₀. We cannot conclude that there has been a significant increase in the mean domestic airfare for business travel for the one-year period. RejectH₀. We can conclude that there has been a significant increase in the mean domestic airfare for business travel for the one-year period.Do not rejectH₀. We cannot 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? (Round your answer to one decimal place.) %
