Document Summary
Uses- #1 (matching pairs: from the data, compute the differences, assign a +" to positive outcomes, assign a - to negative outcomes, ignore if 0. 40 x= number of less frequent sign= 1 n=5 (because you forget about the pair that equaled 0) Uses the sign test with the sample data in the table to test the claim that there is no difference between taxi-out times and taxi-in times. *now start hypothesis test: there is no difference between taxi-in and taxi-out times (out - in = 0, there is no difference (out - in 0, h0: out-in =0. H1: out-in 0: = 0. 05, x, x=0. *determine if the is 1-tail or 2-tail* (if h1 has then it is 2-tail) Use table a-7 ( nd the intersection of n and ) 2: there is suf cient evidence to warrant rejection of the claim that there is no difference.
