Given that We have to conduct hypothesis testing for the claim that there is difference in cost between flights scheduled one day in advance and those scheduled 30 days in advance.Using Excel formula critical value At level of significance=0.05 and degree of freedom (df)=12 Formula Excel =T.INV.2T(0.05,12) =2.179 Decision: Since t calculated value=4.68 is greater than t critical value=2.179 so we reject the null hypothesis and concluded that there is sufficient evidence to support the claim that there is difference in cost between flights scheduled one day in advance and those scheduled 30 days in advance....
