(b) in column b or c of the z tables, find the specified rel. f or the rel. f converted from the percentile, identify the corresponding z at the proportion, transform the z into its raw score, and that score is the cutoff score. 13. ∑X = 103, ∑X² = 931, and N = 12, So S x = 1.98 and X = 8.58 a. For x=10, z=(10-8.58)/1.98 =+.72 b. For x=6, z=(6-8.58)/1.98=-1.30 14. (a) 11 (b) 7.63...
