A point in the x-y plane is represented by its x-coordinate and y-coordinate. Design a class, “pointType”, that can store and process a point in the x-y plane. You should then perform operations on the point, such as setting the coordinates of the point, printing the coordinates of the point, returning thex-coordinate, and returning the y-coordinate. Also, write a program to testvarious operations on the point. x-y plane and you designed the class to capture the properties of a point...

13. Interpreting the intercept in a simple linear regression model is: * (A) reasonable if the sample contains values of x around the origin. (B) not reasonable because researchers are interested in the effect of a change in x on the change in y. (C) reasonable if the intercept’s p-value is less than 0.05. (D) not reasonable because it is always meaningless. 14. Which of the following is NOT one of the assumptions necessary for simple linear regressions?: * (A)...

How should we describe a line in space using Algebra? Hint: 1. We can think of a plane as a collection of vectors in space which satisfies an equation of the form ax + by + cz = d. False, because we can move vectors around, which will mess up the plane. 2. We can think of a plane as a collection of vectors in space whose starting point must be at the origin which satisfies an equation of the...

The equation for a straight line between two variables, xx and yy, is y=mx+by=mx+b. In this equation, mm is the slope of the line and bb is the yy-intercept (the point at which the straight line crosses the yy-axis). When m<0m<0, the line has a negative slope. When m>0m>0, the line has a positive slope. The correlation coefficient, rr, can be used to calculate the values of mm and bb in a linear regression. First, use the values you have...
