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

An administrator at a college claims that the mean SAT Mathematics score of incoming students is 520. You find that in a random sample of 45 incoming students, the mean SAT Mathematics score is 511 with a standard deviation of 48.65. Assume the population of scores are normally distributed. Suppose you perform a hypothesis test to determine whether the mean SAT Mathematics score of incoming students is less than 520. What is the P-value for this hypothesis test? Round the...

18. Scores this year on the SAT mathematics test (SAT-M) for students taking the test for the first time are believed to be Normally distributed with mean 4. For students taking the test for the second time, this year's scores are also believed to be Normally distributed but with a possibly different mean 42. We wish to estimate the difference - A random sample of the SAT-M scores of 100 students who took the test for the first time this...

The SAT scores of students who took the SAT test in 2010 were normally distributed with a mean of 1509 and a standard deviation of 312. What proportion of student scored below 1805 on this SAT? What score is need on this test to be in the top 10% of all test takers?
The mean SAT score in mathematics, u, is 512. The standard deviation of these scores is...
The mean SAT score in mathematics, u, is 512. The standard deviation of these scores is 25. A special preparation course claims that its graduates will score higher, on average, than the mean score 512. A random sample of 25 students completed the course, and their mean SAT score in mathematics was 520. Assume that the population is normally distributed. At the 0.1 level of significance, can we conclude that the preparation course does what it claims? Assume that the...
