a. To determine Perform a complete simple linear regression analysis of the relationship between coefficient of restitution ( y ) and impact speed ( x ). Write all the conclusions. Explanation It is given that the two variables for investigating the impact of dropping ping-pong balls are coefficient of restitution, COR ( y ) and speed at impact ( x ). Out of 19 dropped balls, 10 buckled at impact. Software Procedure: Step-by-step procedure to obtain simple linear regression line using MINITAB software: Select Stat > Regression > Regression > Fit Regression Model. In Response , choose Cor y . In Continuous predictor , choose Speed x . Click OK . The MINITAB output is given below. Here, β 1 is the slope of the regression line. The hypotheses to determine whether there is a linear relationship between coefficient of restitution and impact speed are given below. Null hypothesis: H 0 : β 1 = 0 That is, there is no linear relationship between coefficient of restitution and impact speed b. To determine Explain whether the data support the researcher’s belief.

Equations and Inequations

Equations and inequalities describe the relationship between two mathematical expressions.

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
