In recent years, SAT scores are approximately normal with a mean of 1100 and a SD of 130, while ACT scores are also approximately normal with a mean of 22 and a SD of 6.5. Without any studying, you took both tests and scored 1250 on the SAT and 24 on the ACT.Did you do better on the SAT or the ACT? Make sure to find the percentile (what percent of the test takers scored lower than you?) of each score and compare. b) You know you can do better, so you plan to spend the entire summer preparing to retake the SAT, and you’re aiming to score in the 97th percentile. What score will put you in the 97th percentile?

Scores on the SAT have an approximately normal distribution. THe mean SAT score is 1060 and a standard deviation of 195. Would it be unusual for someone to score a 1250 on the SAT? Explain and show using probability.
Not ACT and SAT scores are both known to be normally distributed. In 2010, the mean and standard deviation for the ACT were ye21 and o-7, respectively. The mean and standard devlation for the SAT were #1510 and ơ-310, respectively a. what ACT score would place a student in the same percentile as a student who scored 1970 on the SAT in 20107 (In other words, what ACT score is 'equivalent to an SAT score of 19707) Round your answer...
Mean and std dev of SAT scores of first year UCF students are mean =μ =1500, Std Dev = σ = 150, distribution is approximately bell-shaped symmetric. What percentage of students scored between 1350 and 1800? Find the minimum score of a student who scored among the top 2.5% student? Find the 16th percentile SAT score
SAT scores are approximately normal with mean 560 and standard deviation 105. In a school, there are 200 students. What is the probability the average score of 200 students will be at least 580?

Round your answer to 4 decimal places. b. Suppose that you choose a simple random sample of 16 students who took the SAT mathematics section and find the sample mean x of their scores. Which of the following best describes what you would expect? The sample mean will be...
(13 points) Scores on the GRE. A college senior who took the Graduate Record Examination exam scored 620 on the Verbal Reasoning section and 750 on the Quantitative Reasoning section. The mean score for Verbal Reasoning section was 467 with a standard deviation of 109, and the mean score for the Quantitative Reasoning was 441 with a standard deviation of 155. Suppose that both distributions are nearly normal. Round calculated answers to 4 decimal places unless directed otherwise. 1. Write...
Scores on the math portion of the SAT (SAT-M) in a recent year have followed a normal distribution with mean μ = 507 and standard deviation σ = 111. What is the probability that the mean SAT-M score of a random sample of 4 students who took the test that year is more than 600? Explain why you can solve this problem, even though the sample size (n = 4) is very low.
