: tool can be used ?
: a.Pareto dagram b.ANOVA c.t distribution d.Regression analysis
: (1)b+d (2)a+b (3)b+d (4)a+c (5)a+b+d (6)none of above
: 2.A single replicate of 2^2 factorial design has 4 reatments.Since
: the time limitation, the 4 treatments should be performed by two
: operators. Which experimentaldesign is appropriate ?
: (1)RBD (2)factorial design (3)fractional factorial design
: (4)confounding design
: 3.To test if two independent population means are same, which
: statistic can be used ?
: a. Mann-Whitney statistic b.paired t statistic
: c.Z statistic d.Wilcoxon signed rank
: (1)a (2)b (3)c (4)a+c (5)c+d (6)b+c (7)none of above

: d.F statistic in ANOVA (RBD)
: (1)a (2)b (3)c (4)d (5)a+d (6)b+d (7)a+c (8)b+c
: 6.About the F statistic, which one is incorrect ?
: (1)used in ANOVA (2)inference for (變異數2/變異數1)
: (3)t^2(v) = F(v,1) (4)F(1-a)(v1,v2) = 1/F(a)(v2,va)
