In order to be accepted into a top-level university, applicants must score within the top 10% on an entrance exam. Given that scores on the exam have an approximate normal distribution with a mean of 75 and a standard deviation of 11, what is the lowest possible score (rounded to the closest integer) a student needs in order to qualify for acceptance into this university?
The average score in the final exam of a course is 65 and the standard deviation is 10. a) Give an upper bound on the probability of a student scoring more than 95? b) Suppose the scores follow a normal distribution. Compute the probability of a student scoring more than 95 and compare it to the bound obtained in a)
If the mean exam score of a class was 75%, with a standard deviation of 15%, what percent of students would be expected score at or higher than 92%? Assume that the distribution of the scores is normal and the variable is random.
If SAT scores follow normal distribution with average of 500 and a standard deviation of 50, then: What is the probability that a score of randomly selected student will be between 400 and 600?
9. (15.24) The length of human pregnancies from conception to birth varies according to a distribution that is approximately Normal with mean 266 days and standard deviation 16 days.

Scores on a standardized exam are known to follow a normal distribution with standard deviation = 8.2. A researcher randomly selects 100 students and computes their average score. he reports that the mean score is 83, with a margin of error of 1.436. How confident are you that the mean score for all students taking the exam is in the interval (81.564; 84.436)?
The average score of students taking a statistics final was 70 with a standard deviation of 5. Assuming a normal distribution, what is the probability that a student scored less than 65?
Almost all medical schools in the United States require students to take the Medical College Admission Test (MCAT). To estimate the mean score μ of those who took the MCAT on your campus, you will obtain the scores of an SRS of students. The scores follow a Normal distribution, and from published information you know that the standard deviation is 10.8. Suppose that, unknown to you, the mean score of those taking the MCAT on your campus is 500. In...
