Use x, your sampled mean from Question 1(c-i) and your population standard deviation σx from Question 1(b), to calculate the 90% confidence interval (CI) for μageCovid. Show setup/work! Does the interval include the current median age of all people in South Korea, 42.3 years? (2 points) There are 309 students this term completing this same assignment. Assuming they calculated their respective CI correctly (recall everyone took their own random sample of 50 patients), about how many students do we expect...
