The scores on the entrance exam at a well-known, exclusive law school are normally distributed with a mean score of 114 and a standard deviation equal to 76. At what value should the lowest passing score be set if the school wishes only 2.5 percent of those taking the test to pass?

The scores on the entrance exam at a well-known, exclusive law school are normally distributed with a mean score of 130 and a standard deviation equal to 53. At what value should the lowest passing score be set if the school wishes only 2.5 percent of those taking the test to pass? (Round your answer to nearest whole number.) Set lowest passing score to: ?
Exercise 2 The scores on the entrance exam at an exclusive university in Bellevue are normally distributed with a mean score of 150 and a standard deviation equals to 40. Sketch the distribution of the scores (you can draw it manually), find the probability and show your calculations, that a randomly selected applicant has a score: a. Under 100 b. Under 50 c. Over 180 d. Between 110 and 200 e. Within 1.5 standard deviations of the mean f. What...
7. Scores on a recent national Mathematics exam were normally distributed with a mean of 82 and a standard deviation of 7. A. What is the probability that a randomly selected exam score is less than 70 B. What is the probability that a randomly selected exam score is greater than 90? C. If the top 2.5% of test scores receive Merit awards, what is the lowest score necessary to receive a merit award?
the scores on the accuplacer test and High School GPAs are normally distributed. The Accuplacer test had a mean of 40 and a standard deviation of 10. High School GPAs had a mean of 2.5 and a standard deviation of 0.1. What high school GPA do you need to equal a score of 44 on the Accuplacer test? Give answer to two decimal places
Problem 3: Scores on an exam are assumed to be normally distributed with mean /u = 75 and variance a2 = 25 (1) What is the probability that a person taking the examination scores higher than 70? (2) Suppose that students scoring in the top 10.03% of this distribution are to receive an A grade. What is the minimum score a student must achieve to earn an A grade? (3) What must be the cutoff point for passing the examination...
The Law School Admission Test (LSAT) is designed so that test scores are normally distributed. The mean LSAT score for the population of all test-takers in 2005 was 154.35, with a standard deviation of 5.62. Calculate the value of the standard error of the mean for the sampling distribution for 100 samples.
A civil service exam yields scores which are normally distributed with a mean of 81 and a standard deviation of 5.5. If the civil service wishes to set a cut-off score on the exam so that 15% of the test takers fail the exam, what should the cut-off score be? Remember to round your z-value to 2 decimal places. Select one: A. 75.28 B. 86.72 C. 60.24 D. 64.56 E. None of the above
Scores on a recent national statistics exam were normally distributed with a mean of 88 and a standard deviation of 2. 1. What is the probability that a randomly selected exam will have a score of at least 85? 2. What percentage of exams will have scores between 89 and 92? 3. If the top 5% of test scores receive merit awards, what is the lowest score eligible for an award? I do not understand how to compute probability.
The Law School Admission Test (LSAT) is designed so that test scores are normally distributed. The mean LSAT score for the population of all test-takers in 2005 was 154.35, with a standard deviation of 5.62. If you drew all possible random samples of size 100 from the population of LSAT test-takers and plotted the values of the mean from each sample, the resulting distribution would be the sampling distribution of the mean. Based on Centeral Limit Theorium, What is the...
(4)Five hundred students from a local high school took a college entrance examination. Historical data from the school record show that the standard deviation of test scores is 40. A random sample of thirty- six students is taken from the entire population of 500 students. The mean test score for the sample is three hundred eighty. Find (a) 95% confidence interval for the unknown population mean test score. (b) 95% confidence interval for the unknown population mean test score if...
