Olivia believes a different percentage of Starbucks’ customers regularly make purchases using a mobile app. Olivia surveys a random sample of 200 Starbucks’ customers and finds that 102 of these customers regularly use a mobile app to make purchases. Olivia proceeds to conduct a hypothesis test by calculating the following test statistic. She reports the final P-value as being 0.1357. What is wrong with the way in which Olivia conducted this hypothesis test? A. Nothing is wrong. B. The test statistic should have been multiplied by two before finding the resulting P-value. C. Instead of using the sample size of 200 in the denominator of the test statistic, the sample size of 102 should have been used. D. The P-value should be 0.2714 instead of 0.1357. E. The numerator of the test statistic should be “0.47 – 0.51” instead of “0.51 – 0.47.”

I have a group project that has us creating a network for a business which is DC Water. The network must include layers 1, 2, and 3. The network design will need to go up to layer 7, which is the focus of the course. In this course, we are adding and configuring servers in active directory. I am struggling with designing a network for this project as I struggle greatly with networking. The following is an outline for what is required from layers 1, 2, and 3. I would like help with the network design of a large business that has 1000 employees and has a main office, two branch offices, a wastewater plant, and out-of-office employees. The "why" of the network setup is the most important part. Thank you for your help. Project Phase 1 Outline for Phase 1 Company Information Locations (sites, branch offices) Number of employees Industry/market Services provided/products manufactured.
