The Human Resource Department at Neumann University would like to examine the relationship between a faculty member’s performance rating (measured on a scale of 1–20) and his or her annual salary increase. The following table shows these data for eight randomly selected faculty members. These data can also be found in the Excel file Neumann.xlsx.

Rating Increase ($) Rating Increase ($)

16 2,400 15 2,000 18 2,500 15 2,600 12 1,800 17 2,000 13 1,700 16 1,900

a. Calculate the Spearman rank-order correlation coefficient.

b. Perform a hypothesis test to determine if the population rank correlation coefficient is more than zero using a = 0.05.
