Last semester, Bonnie took a different Biology teacher than her friend Tony. After the final exam, they compared test scores. Bonnie earned an 83 (mean = 75.6, sd = 5), and Tony earned an 87 (mean = 80.3, sd = 7). Who did better? Why?
A mathematics professor lost a test paper belonging to one of her students. She remembered that the mean score for the class of 20 was 81 and that the sum of the 19 other scores was 1530. What was the grade on the paper she lost?
A student has an average of 81 on four equally weighted tests she has taken in her statistics class. What grade must she receive on her fifth test if she needs an average score of 83? Answer is 91? Can you help me to explain to me step by step?
