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...

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...
