Big Pharma is currently selling a migraine medication called Go Away, Migraine. Suppose that this product works for 80% of all people who use it.   Suppose you choose one random sample of 350 people from the population of people who buy the product. The sample proportion of people for whom the product worked is 0.75. Determine the z-score for this sample proportion.

The next few questions involve scores on the Graduate Record Examination (GRE). The information will be repeated for each question.   Scores on the verbal portion of the GRE follow a normal distribution with a mean of 550 and standard deviation of 120.   Question: The middle 95% of the scores fall between a low score of [low] and a high score of [high].

Given a normal distribution, determine the z-score that has an area to its left of 0.8212.
