The personality characteristics of business leaders (e.g., CEOs) are related to the operations of the businesses that they lead (Oreg & Berson, 2018). Traits like openness to experience are related to positive financial outcomes and other traits are related to negative financial outcomes for their businesses. Suppose that a board of directors is interested in evaluating the personality of their leadership. Among a sample of n = 16 managers, the sample mean of the openness to experiences dimension of personality was M = 4.50. Assuming that μ = 4.24 and σ = 1.05 (Cobb-Clark & Schurer, 2012), use a two-tailed hypothesis test with α = .05 to test the hypothesis that this company’s business leaders’ openness to experience is different from the population.
