Regression?If the methods of this section are used with paired sample data, and the conclusion is that there is sufficient evidence to support the claim of a correlation between the two variables, can we use the methods of Section 10-3 to find the regression equation that can be used for predictions? Why or why not?

Solution 1BSC Step 1 It cannot be used to find the regression line by the method explained in Section 10.3. Because the rank correlation test yields the result that there exists correlation between the two variables. Step 2 The reasons are given below, 1. The rank correlation test does not require the data to be normally distributed. 2. Here fixed value is x and y.then for each fixed value of x, the corresponding y value. So,x and y values should have a normal distribution is one of the requirements in finding the equation of a regression line. 3. From the above in section 10.3 the method explained. So, In section 10.3 will get affected for too extreme departure from normal distribution.
