Suppose you wish to compare the reaction times of people exposed to six differentstimuli. A reaction time measurement is obtained by subjecting a person to a stimu-lus and then measuring the time until the person presents some specified reaction. Theobjective of the experiment is to determine whether differences exist in the reactiontimes for the stimuli used in the experiment. To eliminate the person-to-person vari-ation in reaction time, four persons participated in the experiment and each person'sreaction time (in seconds) was measured for each of the six stimuli. The data are givenin Table 15.10 (ranks of the observations are shown in parentheses). Use the Fried-man F₁-test to determine whether the data present sufficient evidence to indicate dif-ferences in the distributions of reaction times for the six stimuli. Test using a = .05.Reaction Times to Six StimuliSubject1234Rank Sum1.6 (2.5).7 (3.5).9 (3).5 (2)T₁ == 112.9 (6)1.1 (6)1.3 (6).7 (5)T₂ = 23Stimulus3.8 (5).7 (3.5)1.0 (4.5).8 (6)T3 = 194.7 (4).8 (5)1.0 (4.5).6 (3.5)T4 = 175.5 (1).5 (1.5)7 (1).4 (1)T5 == 4.56.6 (2.5).5 (1.5).8 (2).6 (3.5)= 9.5T6 =

How often do you go out dancing? This question was asked by a professional survey group on behalf of the National Arts Survey. A random sample of n1 = 97 single men showed that r1 = 24 went out dancing occasionally. Another random sample of n2 = 93 single women showed that r2 = 18 went out dancing occasionally. Note: For degrees of freedom d.f. not in the Student's t table, use the closest d.f. that is smaller. In some situations, this choice of d.f. may increase the P-value a small amount and thereby produce a slightly more "conservative" answer.
