A police academy has just brought in a batch of new recruits.  All recruits are given an aptitude test and a fitness test. Suppose a researcher wants to know if there is a significant difference in aptitude scores based on a recruits’ fitness level. Recruits are ranked on a scale of 1 – 3 for fitness (1 = lowest fitness category, 3 = highest fitness category). Using “ApScore” as your dependent variable and “FitGroup” as your independent variable, conduct a One-Way, Between Subjects, ANOVA, at α = 0.05, to see if there is a significant difference on the aptitude test between fitness groups.    Identify the correct written form of the null hypothesis   A. The mean fitness score between the three aptitude tests are NOT equal B. The mean aptitude score between the three fitness groups are NOT equal C. The mean aptitude score between the three fitness groups are equal D. The mean fitness score between the three aptitude tests are equal
