A math teacher claims that she has developed a review course that increases the scores of students on the math portion of a college entrance exam. Based on data from the administrator of the exam, scores are normally distributed with u=519. The teacher obtains a random sample of 1800 students, puts them through the review class, and finds that the mean math score of the 1800 students is 525 with a standard deviation of 115. Complete parts (a) through (d) below. B. Ho: u=519, H,: p> 519 OC. Ho: u<519, H,: >519 OD. Ho: u>519, H,: u#519 (b) Test the hypothesis at the a=0.10 level of significance. Is a mean math score of 525 statistically significantly higher than 519? Conduct a hypothesis test using the P-value approach. Find the test statistic. 6-0
