Microsoft periodically issues a Security Bulletin that re-ports the software affected by the vulnerability. In a sample of 50 bulletins issued in a recent year, 32 reported a security problem with Microsoft Windows. a. Find a point estimate of the proportion of security bulletins issued that reported a problem with Windows during the year. b. Find an interval estimate for the proportion, part a. Use a 90% confidence interval. c. Practically interpret the confidence interval, part b. Your answer should begin with, "We are 90% confident .. ".
An article compared five different methods for teaching descriptive statistics. The five methods were traditional lecture and discussion, programmed textbook instruction, programmed text with lectures computer instruction, and computer instruction with lectures. 60 students were randomly assigned, 12 to each method. After completing the course, students took a 1-hour exam. We are interested in finding out if the average test scores are different for the different teaching methods. The p-value of the test is 0.0372. What is the conclusion of the test if the level of significance is αα=0.10? There is enough evidence to conclude that all five group means are significantly different from each other. There is not enough evidence to conclude that all five group means are sigificantly different from one another. There is enough evidence to conclude that at least one group mean is significantly different from others. There is not enough evidence to conclude that at least one…
