Multiple Regression Analysis Was Used to Study How an Individual's $\alpha$

question 2

Essay

Multiple regression analysis was used to study how an individual's income (Y in thousands of dollars) is influenced by age (X₁ in years), level of education (X₂ ranging from 1 to 5), and the person's gender (X₃ where 0 =female and 1=male). The following is a partial result of a computer program that was used on a sample of 20 individuals. $Multiple regression analysis was used to study how an individual's income (Y in thousands of dollars) is influenced by age (X1 in years), level of education (X2 ranging from 1 to 5), and the person's gender (X3 where 0 =female and 1=male). The following is a partial result of a computer program that was used on a sample of 20 individuals. a.Compute the coefficient of determination. b.Perform a t test and determine whether or not the coefficient of the variable level of education (i.e., X2) is significantly different from zero. Let \alpha = 0.05. c.At \alpha = 0.05, perform an F test and determine whether or not the regression model is significant. d.As you note the coefficient of X3 is -0.510. Fully interpret the meaning of this coefficient.$
a.Compute the coefficient of determination.
b.Perform a t test and determine whether or not the coefficient of the variable "level of education" (i.e., X₂) is significantly different from zero. Let $\alpha$ = 0.05.
c.At $\alpha$ = 0.05, perform an F test and determine whether or not the regression model is significant.
d.As you note the coefficient of X₃ is -0.510. Fully interpret the meaning of this coefficient.
