An Employee Value Proposition (EVP) is about defining the essence of a company. The EVP is the value an employee receives from the employer; it defines the commitment the company will make to develop the employee in exchange for the effort the employee puts in to benefit the company. But do all agree on what makes a unique and compelling EVP? A study showed that 14% of business executives, 38% of HR leaders, and 33% of employees say that compensation (pay and rewards) makes for a unique and compelling EVP.

Assume that 200 individuals within each business group were surveyed.

a. Is there evidence of a difference among business groups with respect to the proportion that say compensation (pay and rewards) makes for a unique and compelling EVP?

b. Determine the p-value in (a) and interpret its meaning.

c. If appropriate, use the Marascuilo procedure and α = 0.05 to determine which business groups differ in the proportion that say compensation (pay and rewards) makes for a unique and compelling EVP.
