We are studying the octane number of two unleaded gasoline. Here is a table that summarizes the results of the study: Number Мean Standard Deviation Formula No 1 18 86.5 1.82 Formula No 2 44 84.6 1.01 a) Do the two formulas have the same dispersion? Use an a of risk of 10%. Critical Value: P Value: Check the box corresponding to the tested hypothesis: Ho: S1= S2 Ho: 0z= 02 O 2 H1: S1 # S2 Ho: 01= 02 H1: 0;<02 Ho: S1= S2 O 3 4 H1: S1< S2 Ho: 01= 02 H1: 0;>02 Ho: S1= S2 05 06 H1: S1 > S2 or None of the answers: On the basis of the observed results, we can conclude that .. I Both formulas have the same dispersion II The two formulas do not have the same dispersion b) Does formula # 1 have a higher octane number than formula # 2. Use a risk of a of 1%. Critical Value: P Value: Degree of Freedom: Check the box corresponding to the tested hypothesis:
