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 v th a standard deviation of 115. Complete parts (a) through (d) below. (d) Test the hypothesis at the 0.10 level of significance withn3350 students. Assume that the sample mean is still 525 and the sample standard deviation is still 115. Is Conduct a hypothesis test using the P-value approach. sample mean of 525 significantly more than 519? Find the test statistic. to =0 (Round to two decimal places as needed.) More
