Quantitative GRE scores In recent years, scores on the quantitative portion of the GRE have had a mean of 591 and standard deviation of 148.
a. If the distribution is normal, about what proportion of quantitative scores fall (i) below 700 and (ii) above 700?
b. In fact, the distribution is not exactly normal. How can you tell this from the values of the mean and standard deviation, given that the scores fall between 200 and 800?
c. Describe the shape, mean, and standard deviation of the sampling distribution of the sample mean quantitative exam score for a random sample of 100 people who take this exam.
