The state of virginia has implemented a standard of learning (sol) test that all public school students must pass before they can graduate from high school. a passing grade is 75. montgomery county high school administrators want to gauge how well their students might do on the sol test, but they don’t want to take the time to test the whole student population. instead, they selected 20 students at random and gave them the test. the results are as follows: 83 79 56 93 48 92 37 45 72 71 92 71 66 83 81 80 58 95 67 78 assume that sol test scores are normally distributed. a. compute the mean and standard deviation for these data. b. determine the probability that a student at the high school will pass the test. c. how many percent of students will receive a score between 75 and 95? d. what score will put a student in the bottom 15% in sol score among all students who take the test? e. what score will put a student in the top 2% in sol score among all students who take the test? g
