Introduction What is statistics about •Statistics is the science of collecting, organizing, summarizing, and analyzing information to draw a conclusion and answer questions. •In addition, statistics is about providing a measure of confidence in any conclusions. 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 μ=511. The teacher obtains a random sample of 36 students, puts them through the review class, and finds that mean of the math score of the 36 studen̅ 530 with s=115. Test the hypothesis at the α=0.05 level What is the population of the study (The target group of the study.) What is th
