Type yоur аnswers аnd suppоrting wоrk below. Lаbel each part for the appropriate letter. Incorrect answers with supporting work can receive partial credit. Glaucoma is an eye disease that is manifested by high intraocular pressure (IOP). The distribution of IOP in the general population is normally distributed with a mean of 16.5 mm Hg and a standard deviation of 3.2 mm Hg. Use this information to answer the questions that follow. Round answers to four decimal places. A person is diagnosed with glaucoma if their IOP is above 22 mm Hg. What is the probability a randomly selected person from the general population has glaucoma? (4 pts) The highest 20% IOPs are a minimum of what value? (4 pts) Suppose a random sample of four people from the general population is selected. The mean IOP for this sample calculated to be 14.5 mm Hg. What is the probability that the mean cholesterol level IOP from a sample of four is less than 14.5 mm Hg? (6 pts)
