β is the slope that equals the average change of the dependent variable (Y) as the independent variable (X) increases by one.
α is equal to the Y-intercept, or the point at which the regression line crosses the Y-axis, when X is equal to zero.
Here, ŷ represents the expected value of the dependent variable for a given value of X, which represents the independent variable. To find the line of best fit, use the following equation: In single variable linear regression analysis, the relationship between a dependent variable and an independent variable is evaluated by identifying the line of best fit. Linear regression analysis is used for two main purposes: to identify and evaluate the relationship between two variables and forecast a variable based on its relationship to another one.

Hypothesis testing is a complex yet highly valuable statistical method for business.

The alternative hypothesis (denoted by H₁) represents the theory or assumption being tested and is the opposite of the null hypothesis. A hypothesis test always starts by assuming the null hypothesis is true and then testing to see if it can be nullified. The null hypothesis (denoted by H₀) is a statement about the issue at hand, generally based on historical data and conventional wisdom.
