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 the sample of the study (The subset that has similar attributes with the population.) What is the measurement unit in this study (The individual being studied.) What are the parameters (Measurements about the population.) What are the statistics (Measurements about the sample.) In randomized, double­blind clinical trials of a new vaccine, monkeys were randomly divided into two groups. Subjects in group 1 received the new vaccine while subjects in group 2 received a control vaccine. After the first dose, 115 of 701 subjects in group 1 experienced fever as a side effect. After the first dose, 68 of 609 of the subjects in group 2 experienced fever as a side effect. 1)Construct a 99 % confidence interval for the difference between the two population proportions, p_1-p_2. Construct a
