On a standard test of optimism scores of patients diagnosed with a particular disease are normally distributed with a mean of 20 and a standard deviation of 5. Use the normal curve table to determine the score a patient needs to be included among the top 5%, among the top 20% , and among the bottom 10% of optimism scores. Can you illustrate your answers with a sketch?
