SAT scores are distributed with a mean of 1,500 and a standard deviation of 300. You are interested in estimating the average SAT score of first year students at your college. If you would like to limit the margin of error of your 95% confidence interval to 25 points, how many students should you sample? Box 1: Enter your answer as an integer or decimal number. Examples: 3, -4, 5.5172 Enter DNE for Does Not Exist, oo for Infinity

SAT scores are distributed with a mean of 1,500 and a standard deviation of 295. You are interested in estimating the average SAT score of first year students at your college. If you would like to limit the margin of error of your confidence interval to 20 points with 90 percent confidence, how many students should you sample? (Round up to a whole number of students.)
SAT scores are normally distributed with a mean of 1,500 and a standard deviation of 300. An administrator at a college is interested in estimating the average SAT score of first-year students. If the administrator would like to limit the margin of error of the 98% confidence interval to 5 points, how many students should the administrator sample? Make sure to give a whole number answer.
please show how its done on TI-64 1. SAT scores are distributed with a mean of 1,500 and a standard deviation of 300. You are interested in estimating the average SAT score of first year students at your college. If you would like to limit the margin of error of your 95% confidence interval to 25 points, how many students should you sample? 3. If n=31, ¯xx¯(x-bar)=36, and s=6, construct a confidence interval at a 98% confidence level. Assume the...
The combined SAT scores for students taking the SAT-I test are normally distributed with a mean of 982 and a standard deviation of 192. Explain specifically why we could use the Central Limit Theorem to find the probability that a randomly selected sample of 9 students who took the SAT-I has a mean score between 800-1150 even though the same size is less than 30
the combined SAT scores for the students at a local
high school are normally distributed with a mean of 1466
The combined SAT scores for the students at a local high school are normally distributed with a mean of 1450 and a standard deviation of 302. The local college includes a minimum score of 2265 in its admission requirements. What percentage of students from this school earn scores that satisfy the admission requirement? P(X> 2265) Enter your answer as a...
The SAT scores for students are normally distributed with a mean of 1100 and a standard deviation of 210. What is the probability that a sample of 90 students will have an average score between 1050 and 1120? Round your answer to 3 decimal places.
Scores by women on the SAT-1 test are normally distributed with a mean of 988 and a standard deviation of 202. Scores by women on the ACT test are normally distributed with a mean of 20.9 and a standard deviation of 4.6. If a women gets a SAT score that is the 77th percentile, find her actual SAT score and her equivalent ACT score.
SAT scores are normally distributed, with a mean of 500 and a standard deviation of 100. Xiomara took the SAT and scored 650. 8) Based on this information, Xiomara’s score was equal to or higher than what percentage of the other students?
