Which of these tests must be checked first? Conduct this test at the .05 level of significance. State your conclusion and explain how you arrived at that conclusion. Interpret the result of the test as it applies to personality dimensions and sales performance.

What is a residual for a multiple regression model and the data that is used to create it? Select one. A statistic that is used to evaluate the significance of the multiple regression model A statistic that explains the relationship between response and predictor variables The predicted value of the response variable using the multiple regression model The difference between the actual value of the response variable and the corresponding predicted value (regression error) using the multiple regression model

Data of variable-A is collected as shown to the right. Is the mean of Variable-A less than 80? State null hypothesis and choose level of significance, a = 0.05. (Use Excel ttest function, provide clear logic and reasoning.)
