The BioPharm company has developed a stress test for college-aged students. Scores on the stress test are approximately normally distributed with a mean of 55 points and a standard deviation of 2 points. Scores of 58 points or higher indicate a high level of stress and are of concern to doctors. A random sample of college-aged students will be selected and each will be given this stress test. Answer the following questions based on the information given.
1. What is the probability that the first randomly selected student has a high level of stress?
2. Given that the first randomly selected student is highly stressed, what is the probability that the next randomly selected doesn’t have a high level of stress?
3. Suppose the stress test is given to six randomly selected college students. What is the probability that exactly two of the six students will have a high level of stress (a score of at least 58 points)?

er claims that she has developed a review course that increases
the scores of students on the math portion of a college entrance
exam. Based on data from the administrator of the exam, scores are
normally distributed with mu equalsμ=517517. The teacher obtains a
random sample of 20002000 students, puts them through the review
class, and finds that the mean math score of the 20002000 students
is 523523 with a standard deviation of 110110. Complete parts (a)
