Which one of the following statements is FALSE regarding parametric and nonparametric classification types of statistical tests? Select one: O a. The chi square test is a non-parametric test, but the t-test and the ANOVA are parametric tests. O b. Non-parametric tests reflect differences in the magnitude of a measure. O c. The chi square test, the t-test, and the ANOVA are also known as "distribution-free" statistics. O d. Non-parametric tests reflect different and independent groups being measured. O e. both A) and D) Of. both B) and C)Q6. What are non-parametric tests? Use sign rank test to solve the given samples.
