1. Thousands of students apply for admission to graduate schools in economics each year with the intention of obtaining a PhD. The mean and standard deviation of these 129 productivity scores were used to compute a z score for each economics program. Harvard University had the highest z score (z=5.08) and hence was the top ranked school; Howard University was ranked last with the lowest z score (z+-0.81).

a. Interpret the z score for Harvard

b. Interpret the z score for Howard

c. The authors of the southern economic journal article note that only 44 out of 129 schools have positive z scores indicating that the distribution of overall productivity is skewed to the right. Do you agree? (check your answer by constructing a histogram for the z scores in the file attached.)
