The Answer is (a) Degrees of freedom: In statistics, degrees of freedom refer to the number of values in the final calculation of a statistic that are free to vary. It is often denoted by the symbol "df" and is used in various statistical tests and analyses.

(b) Estimated regression equation: The estimated regression equation is a mathematical model that represents the relationship between a dependent variable and one or more independent variables. It is typically expressed in the form Y = a + bX, where Y is the dependent variable, X is the independent variable, a is the intercept, and b is the slope.

(c) The Six Steps in Applied Regression Analysis: The six steps in applied regression analysis include: 1) Formulating the research question, 2) Collecting and preparing the data, 3) Exploring and visualizing the data, 4) Fitting the regression model, 5) Assessing the model, and 6) Using the model for prediction or inference.

(d) Ordinary Least Squares: Ordinary Least Squares (OLS) is a method used in regression analysis to estimate the parameters of a linear regression model. It minimizes the sum of the squared differences between the observed and predicted values of the dependent variable.

(e) The meaning of

\beta

₁ in the given equation is not clear and appears to be a string of characters without a specific statistical meaning. It does not correspond to any standard notation or formula in regression analysis.
