Question 8 The relationship between annual salary (in US dollars) and race was estimated as below in a linear format. (White employees were coded as 0 and Non-White employees were coded as 1.) Annual Salary = -17,472 * Non-White + 48,253 (The p-value for the coefficient of Non-White is 0.01.) How can the relationship between race and annual salary be interpreted? A.) White employees are expected to receive 17,472 dollars more than non-white employees. B.) White employees are expected to receive 17,472 dollars less than non-white employees. C.)There is no meaningful difference in annual salary between white and non-white employees from a statistical point of view. D.) White employees are expected to receive 48,253 dollars more than non-white employees.
Problem 2: The research scenario: Do you think there might be a relationships between people’s personality and the profession they pursue? Here’s a fictional set of data that explores that question. There are two personality types in the data, ‘thinkers’ and ‘feelers.’ There are 3 professions. A chi square analysis can examine whether the proportion that is found to be thinkers overall (i.e, across all 3 professions) is similar to the proportion of thinkers among clergy, the proportion of thinkers among physicians, and the proportion of thinkers among lawyers. The following crosstab table shows the “crossed” frequencies for 2 variables: “Myers-Brigg” personality type “T” = “thinking” personality “F” = “feeling” personality “profession” clergy physician…
