Question 9 10 pts Suppose that for a given year, the mean score on the SAT Mathematics Test was 515. The data is assumed to be normally distributed and the population standard deviation is 100. Is there sufficient evidence, at the 0.10 level of significance, to determine if the mean score of 36 SAT scores is less than the mean score for that given year? The 36 SAT scores are listed below as follows: 496 506 507 505 438 499...

The College Board reported in a recent year that the mean math SAT score was 515, with a standard deviation of 116. Results of an earlier study suggest that coached students should have a mean SAT score of approximately 530. A teacher who runs an online coaching program thinks that students coached by his method have a higher mean score than this.

Reports on a student's ACT, SAT, or MCAT usually give the percentile as well as the actual score. The percentile is just the cumulative proportion stated as a percent: the percent of all scores that were lower than this one. In a certain year, the total MCAT scores were close to Normal with mean 25.4 and standard deviation 6.1. A student scored 30. What was the percentile? (Round your answer to the nearest whole number.)
