(a) If you choose one student at random, what is the probability that the student's score is between 505 and 5157 Use Table A, or software to calculate your answer. (Enter your answer rounded to four decimal places.) probability: ? (Enter (b) You sample 36 students. What is the standard deviation of the sampling distribution of their average score your answer rounded to two decimal places. standard deviation: (c) What is the probability that the mean score of your sample is between 505 and 515? (Enter your answer rounded to four decimal places.) probability:
