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. 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 110. Complete parts (a) through (d) below. The teacher obtains (a) State the null and alternative hypotheses. Họ: H = 519 , H,: H > 519 (b) Test the hypothesis at the a = 0.10 level f 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. t6 =0 (Round to two decimal places as needed.)
