random sample of 100 high school seniors from a certain region had a mean reading score of 72.  National norms of reading proficiency for a high school seniors show a distribution of scores with a mean of 75 and a standard deviation of 16. Is it reasonable to consider that the 100 scores obtained from that region came from a population that follows a distribution similar to that of the national norm? a)No, z-value is less than-3 b) Yes, z-value is greater than 3 c) Yes, z-value is -1.875
