10.3.31-T 0.11 of 1 Point Question Help 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 = 520. 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 526 with a standard deviation of 114. Complete parts (a) through (d) below. X Yes, because every increase in score is practically significant. No, because the score became only 1.15% greater. (d) Test the hypothesis at the a = 0.10 level of significance with n = 350 students. Assume that the sample mean is still 526 and the sample standard deviation is still 114. Is a sample mean of 526 significantly more than 520? Conduct a hypothesis test using the P-value approach. Find the test statistic. to = (Round to two decimal places as needed.)
