Two people, one in Los Angeles and one in New York, take the graduate record entrance exam. These were different exams, but we would like to compare their scores. The person in Los Angeles received a 647 while the average 640 with a standard deviation of 20. The person in New York recieved a 570 while the avarage was 560 with a standard deviation of 25. First, calculate the z- score for each person, then indicate who scored higher after standing the scores. Person 2 (new york)??
z score for Person 1 = (647 - 640)/20 = 7/20 = 0.35
z score for Person 2 = (570 - 560)/25 = 0.40
Since z score for Person 2 i.e. person from New York is higher, Person 2 scored higher after standing the scores.

The SAT and ACT college entrance exams are taken by thousands of students each year. The mathematics portions of each of these exams produce scores that are approximately normally distributed. In recent years, SAT mathematics exam scores have averaged 480 with standard deviation 100. The average and standard deviation for ACT mathematics scores are 18 and 6, respectively. (a) An engineering school sets 560 as the minimum SAT math score for new students. What percentage of students will score below...
Sal's satellite company broadcasts TV to subscribers in Los Angeles and New York. The demand functions for each of these two groups are: QNY = 70 -0.25PNY QLA = 110-0.5PLA where Q is in thousands of subscriptions per year and P is the subscription price per year. The cost of providing Q units of service is given by C = 1000 + 40Q where Q = QNY +QLA a. What are the profit-maximizing prices and quantities for the New York...
Assume that scores on the verbal portion of the GRE (Graduate Record Exam) follow the normal distribution with mean score 151 and standard deviation 7 points, while the quantitative portion of the exam has scores following the normal distribution with mean 153 and standard deviation 7.67. Use this information to answer the following: (Please round to two decimal places) a) Find the score of a student who scored in the 80th percentile on the Quantitative Reasoning section of the exam....
A new exam was written to be used as an entrance exam. You took the exam and your score report said that you got a score of 633 points out of 800 possible and that the mean and standard deviation for all test takers is μ = 400 and σ = 100 and the distribution is normal. What percentage of students taking the test scored higher than you did? The department decides to accept all the students who score in...
1) The Graduate Record Examination (GRE) is a standardized test that students usually take before entering graduate school. According to the document Interpreting Your GRE Scores, a publication of the Educational Testing Service, the scores on the verbal portion of the GRE are approximately normally distributed with a mean of 462 points and a standard deviation of 119 points. Find the 90th percentile for this exam score. Please show your work, and steps. If there is a bell curve write one.
Problem 11-5 (Algo) Next week, Super Discount Airlines has a flight from New York to Los Angeles that will be booked to capacity. The airline knows from history that an average of 25 customers (with a standard deviation of 13) cancel their reservation or do not show for the flight. Revenue from a ticket on the flight is $135. If the flight is overbooked, the airline has a policy of getting the customer on the next available flight and giving...
the army gives a battery of exams to all new recruits. one exam measures a person's ability to work with technical machinery. this exam was given to a random sample of 360 new recruits. in the table below x-scores on the test and f is the frequency of new recruits with score x. x 1 2 3 4 5 6 7 8 9 10 f 28 42 79 83 51 36 18 ...
Two standardized tests, test A and test B, use very different scales. Assume that in one year the distribution of scores on test A can be modeled by N(1300,250) and scores on test B can be modeled by N(15, 3). If an applicant to a university has taken test A and scored 1670 and another student has taken test B and scored 19, compare these students' scores using z-values. Which one has a higher relative score? Explain. The Z-value of...
1. Suppose the proportion of the population in favor of a new law is 0.60. (a) Suppose you take a sample of size n = 500. What is the probability that your sample proportion is 0.55 or lower? (b) Suppose that you take a sample of size n = 400 and find the sample proportion ˆp = 0.70. How many standard deviations is ˆp from the mean of the distribution of all sample proportions? 2. A college senior who took...
