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=513. 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 521 with a standard deviation of 117. Complete parts (a) through (d) below. (a) State the null and alternative hypotheses. Let u be the mean score. Choose the correct answer below. O A. Ho: H>513, H,: u#513 O B. Ho: H<513, H,: u>513 O C. Ho: H=513, H,: µ#513 O D. Ho: H=513, H,: µ>513
