2. Find the specified areas for a normal distribution. For a N(15, 5) distribution The area to the right of 28. i) The area to the left of 12. 3. Find the indicated confidence interval. Assume the standard error comes from a bootstrap distribution that is approximately normally distributed. A) A 95% confidence interval for a proportion p if the sample has n= 100 with p^ = 0.43, and the standard error is SE = 0.05. B) A 90% confidence interval for a mean uif the sample has n = 30 and x-bar =23.1 and s = 5.7, and the standard error is SE = 1.04. 2. Find the specified areas for a normal distribution.
