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 p = 522. 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 527 with a standard deviation of 113. Complete parts (a) through (d) below. ..... (a) State the null and alternative hypotheses. Họ:

![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 \( \mu = 522 \). 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 527 with a standard deviation of 113.
