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: ?
The scores on the entrance exam at a well-known, exclusive law school are normally distributed with a mean score of 250 and a standard deviation equal to 89. 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.)
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
All applicants to medical school are required to take an entrance exam. Historically, scores on the exam are known to be normally distributed with mean 99 and standard deviation 8. This year, we observe that a sample of 16 applicants obtains an average score of 97.92. Does this provide evidence that the average of all this year's applicants is less than 99? To answer this question, we do a hypothesis test using a significance level of 0.01. Check all of...
All applicants to medical school are required to take an entrance exam. Historically, scores on the exam are known to be normally distributed with mean 62 and standard deviation 8. This year, we observe that a sample of 17 applicants obtains an average score of 59.91. Does this provide evidence that the average of all this year's applicants is different from 62? To answer this question, we do a hypothesis test using a significance level of 0.01. Check all of...
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
