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 datafrom the administrator of the exam, scores are normally distributed with u = 520. The teacher obtains a random sample of 2200 students, puts them through the reviewclass, and finds that the mean math score of the 2200 students is 525 with a standard deviation of 110. 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= 520, H,: µ> 520%3DB. Ho: μ< 520, H,: μ> 520С.

In other words, does the increase in the scorehave any practical significance?Yes, because every increase in score is practically significant.No, because the score became only 0.96% greater.ARoct
