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 u = 4.24 and o = 1.05 (Cobb-Clark & Schurer, 2012), use a two-tailed hypothesis test with a = .05 to test the hypothesis that this company's business leaders' openness to experience is different from the population.

A financial analyst wants to understand the preference of the people investment strategy. A randomly selected people asked a question about the preference investment on their money either on "real estate" or "stock market". After collecting a data some statistical analysis is done to understand the main question of the analyst. Here is the financial analyst thought: A financial analyst thinks that there is an decreasing ratio on investing the money to "real estate " for last 5 years. In order to test the decrease in the preference of real estate a research is done and the following numbers are collected in 2010 and 2015. 20152010 Number of people asked 250 400 Number of people who prefer real estate 130 180 The analyst claims that there is a decreasing trend for every new year for investing the money to real estate. That means the ratio of people who invest their money to "real estate" in 2015 is less than that of in 2010. (H_{1}) : P 2010 >P 2015 ) Calculate test statistics.

A classification tree is built on the data below to predict whether or not a student will pass a course. The predictor variables include the categorisation of 2nd year marks (categorised as high (H) / medium (M) / or low (L)) and whether or not the majority of lectures were attended (yes (Y) or no (N)). The response is coded as a pass (P) or fail (F). 2nd yr marks Attended Passed N F Y P M F M Y P H H Y P The Shannon-entropy value for passing given the lecture attendance variable is
