please answer all question 9-11
Question 9 2 pts z scores are useful because they: o reduce the probability of Type I and Type Il errors, allow permit the transformation of raw scores into percentiles. o transform linear scores into nonlinear scores, convert nonlinear scores back into linear scores, and allow us to obtain comparisons between nonlinear and linear scores. Pelation to the mean of its underlying population allow comparisons to be made between stores from different distributions, and permit...
