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 value of the mean of the sampling distribution? And Why?

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.

5) The average LSAT score (the standardized test required to apply to law school) in the United States is µ =150 (σ = 10). Also, the LSAT is normally distributed. Use these parameters to answer the following question: • If someone wants to have an LSAT score higher than 90% of all other test-takers, what score do they need to earn?

1) The Law School Admission Test (LSAT) is an examination for prospective law school students. Scores on the LSAT are known to have a normal distribution and a population standard deviation of σ = 10. A random sample of 250 LSAT takers produced a sample mean of 502. What value should be used for the confidence multiplier in a 99% confidence interval for the population mean LSAT score? Group of answer choices 1.960 2.0 2.576 1.645 2) A large supermarket...

A test has been designed so that scores are normally distributed with a mean of 100 and a standard deviation of 15. If a test taker is chosen at random, find the probability that their score on the test will be: less than 76 greater than 137 between 90 and 110 If you want to target test takers who score in the top 7% on the test, you should look for test takers whose score is above what value?

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: ?

For a certain law school, the entering students have an average LSAT score of about 700 with a standard deviation of about 40. The smoothed density histogram of the LSAT scores appears to follow a normal distribution. Sketch a smoothed density histogram (a bell-shaped curve) of the distributions for the LSAT scores. (For this problem, draw this on your own paper. You will not need to submit this graph.) Because this distribution is approximately normal, the mean is equal to...

1. The raw scores on the standardized reading test are normally distributed so the raw scores can be converted into a distribution of Z scores. If we want to mark the lower 5% of the distribution on the Z distribution, what is the Z value that is the cut-off point for that 5% tail region? (Answer with the exact Z value found from the Z table) 2. What would be the cut-off raw score if we want to mark the...

The combined SAT scores for the students at a local high school are normally distributed with a mean of 1541 and a standard deviation of 301. The local college includes a minimum score of 789 in its admission requirements. What percentage of students from this school earn scores that fail to satisfy the admission requirement? P(X < 789) = %
